Software programs are never free of errors and a program
like ENA which is improved permanently there is additionally a risk of integrating new mistakes.
To minize this problem any error which is detected in ENA will be
corrected as soon as possible and a new version with update
information put on this website. Therefore any feedback on ENA is appreciated.

Version 2011 of ENA is finished with several smaller improvements and the following bigger modifications:**14.11.2008**

**1.6.2008**

**1.1.2008**

- In the death rate calculation the counting of subjects which joined, left, were born or died for the total number of subjects is optimized

- A Spanish version is integrated into the program
- Opening and calculating the results of individual mortality data is much faster
- Handling of dates when data is exchanged between computers with different date formats is corrected in the mortality part
- A new questionnaire for
demography and mortality data is integrated

- In the plausibility report the p-level for the check of the
overall age distribution is added and the penalty points for the
standard deviation of WHZ are changed.

- Some default values are changed and redundant information in the plausibility report is removed.
- In the weighted analysis a wrong handling of the age groups under certain circumstances is corrected

- A small error in the calculation of the total number of
subjects for death rates is corrected when the data is entered on the
individual level.

- Tables for overweight children are integrated into the Word Report
- The cut off's in the plausibility reported are updated based on recent experience with a large number of surveys
- An error in the numbers of subjects for age dependent graphs is corrected

- An error in the weight dependent z-scores is corrected when data
is exported to Excel and a correction of the weight of the clothes is
made.

- An error is corrected in Table 3.4 of the Word report (the number of marasmic kwashiorkor children were not shown)

- An error in the options page is corrected when the age or height restriction is applied
- The default installation directory is changed back to c:\ena2011 to avoid problems with the connection to MS Office under Windosws XP

Version 2011 of ENA is finished with several smaller improvements and the following bigger modifications:

- It is possible now to collect mortality data on the individual level and to get more detailed results (sex and age specific death rates, percentages for the cause of death,..).
- A Food Security module is integrated which can allow to find out why the nutritional status in a certain area is bad.
- The MUAC is now fully integrated in the training, results and plausibility part of ENA and the z-scores from the new WHO standards are automatically added when the data of the survey is exported to Excel.
- The type of measurement (height or length) can be entered and the data is automatically corrected when it is not done in the standard way (e.g. a child measured standing when the age is < 2 years)
- It is possible now to do a weighted analysis of the data. For each subject a weight can be entered and a report is given out in Excel similar to the WHO tables.
- With a statistical calculator it is possible to do descriptive statistics for any variable broken down by cut off's or ranges. Additionally crosstables between any of the variables and prevalence rates with design effect adjusted confidence intervals can be calculated.

- Changes in the planning sheet: correction for small population size, assigning reserve clusters at the same time when the other clusters are chosen
- Changes in result sheet: Adding graphs for cumulative distribution and probability plots, adding results if cases (WHZ<-2,..) are randomly distributed or aggregated in clusters, the reference (WHO, NCHS) can be changed in the results sheet and not only in the data entry sheet
- Changes in mortality part: when household and cluster numbers are taken over from the anthropometry sheet households with two children are put together
- Changes in options: the range for exclusion of values can be modified for both exclusion procedures (from reference mean and from observed mean), the expected proportion for girls and boys for the plausibility report can be adjusted

- Major revision of the Plausibility Report
- Integration of an automatic change of the language to French (Thanks to Gwenola Desplats for the first translation and Yvonne Grellety and Melody Tondeur for further changes)
- Automatic connection of .as with ENA, improvement of flagging
procedure, calculation of numbers of households which have to be
visited,...

- Modification of the calculation of the confidence intervals => using a SUDAAN procedure
- Automatic report is extended with tables for underweight/stunting, design effects, mean values and valid z-scores
- In the exported file to Excel automatically both z-scores (NCHS and WHO) are added to the table

**15.10.2007**

- Household numbers in the mortality data can be modified
- Different surveys can be merged
- The number of enumerators can be increased up to 20
- The survey can be sorted for two variables and not only one
- Children outside a certain age range (e.g. <6 months and >59 months) can be automatically excluded from the evaluation

**21.8.2007**

- The file language.dat contains all text strings of the program to allow an easy translation of the program in other languages

**7.6.2007**

- The name of the program is changed to ENA to differentiate it better from the general nutrition software NutriSurvey
- In the Results tab sheet it is possible to exclude automatically z-scores which are outside a plausible range
- The number of missing values and the mean z-score is presented in the textbox of the results
- The cut off's for Kwashiorkor and Marasmus are corrected (from -2 to -3)
- The form for the collection of the mortality data is modified to make it identical to the data entry sheet in the software
- An error in the table for cluster sampling of the Planning sheet which prevented to save the data is corrected
- In the Options some things which are not necessary anymore are removed or deactivated

**8.12.2006**

- The new WHO standards for anthropometry are integrated
- In the Result Tab there is now a table with the main results for the anthropometric indicators and the design effects for anthropometric indicators are given
- Weight dependend z-scores for subjects with edema are not calculated anymore to make the program compatible to Anthro2005 for the new WHO standards
- Smaller things are improved like Ctrl. commands and improvements of the screens

**2****.10.2006**

- In the Mortality data sheet a paste function for data from Excel is integrated
- The entering of data for cluster/sex/edema is directly checked

**5.6.2006**

An error is removed when children are in the database with no data to calculate a weight for age z-score or % of Median.

**16.5.2006**
