Data for: Childhood Acute Illness and Nutrition (CHAIN) Network: a multi-site prospective cohort study to identify modifiable risk factors for mortality among acutely ill children in Africa and Asia

This dataset contains the entire data that was collected by the CHAIN prospective cohort study that was run between 01/11/2016 and 31/03/2019. The study was a multi-site longitudinal study that involved 9 sites in 6 countries. During the study, participant demographic, clinical, social, GPS and laboratory data was collected at various timepoints depending on a predetermined study activity schedule. This repository has been organized according to these broader domains. Each folder contains data files for that domain and these are in flat/wide format. Each domain folder has specific subdomain files, for instance, demographic contains anthropometry, dates and outcome flat files. Each folder contains both .csv and .dta (stata data file), however we recommend using the .csv files whenever possible as this is the generated file by the main reproducible script. Further to these folders, a note-to-file folder has been added that contains data cleaning notes for specific unresolvable queries that explain those data. Data dictionaries have been provided in two kinds: a main wide codebook of every variable and a leaner data domains file that contains specific variables per domain.
