**3.6 WellGrowth**

WellGrowth7 app enables the visualisation of inconsistent data through direct comparison of an investigating dataset with a case control dataset. This is achieved through the visual evaluation of inconsistencies in children's growth pattern using the dataset from World Health Organisation8 (WHO) as the case control dataset and dataset generated from Nsukka Medical Centre (NMC). These datasets are stored in the WellGrowth App for further evaluation by the App users.

WellGrowth adopts the average (50th percentile) score of WHO's children growth data for each month from 0 to 12 months in building WHO's growth curve. WHO's children growth data are gotten from children's empirical data such as height and weight at different stages of their growth for a sex matched reference. WellGrowth also integrates children growth data collected from the NMC. The average (50th percentile) score of the different children's weights and lengths in each month as curated from NMC are used to build the NMC/local growth curve. Finally, the individual growth curve is generated from inputs of a child's monthly weight/length as keyed into the WellGrowth input form by the WellGrowth App

user. A visual comparison of growth patterns from WHO to the growth patterns from NMC is used to enable the analysis of inconsistencies in children's growth data from Nsukka Medical Centre. Also, input of a child's growth data is used by WellGrowth app to enable a visual comparison of growth patterns of a Child with WHO's growth curve.

The authors designed WellGrowth for plotting growth pattern graphs from WHO, NMC and user's input data. WellGrowth App adopts colour coding and fault tolerance to enable easier visualisation of inconsistencies in their investigated datasets. For example, the average growth data whose value is less than 2 units from WHO's data value are yellow; the average growth data whose values are greater or equal to 2 and less than 4 are filled with red; while those values are greater or equal to 4 are filled with a yellow colour. Further details of WellGrowth implementations are expected in another publication by the authors.
