Sample Survey
African Research into Kidney Disease (ARK) is a collaboration between researchers at centers in South Africa, Malawi, Uganda and LSHTM studying the best way to define kidney disease and studying its prevalence in large population-representative cohorts.
The do-file combined_ark_data creates 2 versions of the dataset ark_combined_final, one with MEIRU ids retained (_meiruid) and one without (_anon) which was sent to external collaborators (note that the anon version is not suitable for open access). The do-file also creates a listing of iohexol results from both sites from the South African lab. The combined dataset is the all the data from the ARK study which was carried out in Lilongwe and Karonga sites in 2018/2019. The do-file brings data from several tables to have one record per person. The tables used are listed below:
ark_iohex_results : Iohex results file generated by this do-file using excel results lists sent by Jaya in SA lab
arkk_arkq / arkl_arkq : Data from ARK questionnaire (Karonga / Lilongwe)
arkk_consent / arkl_consent : Data from ARK consent form (Karonga / Lilongwe)
arkk_fieldlog / arkl_fieldlog : Data from ARK field log (Karonga / Lilongwe)
arkk_syrweight / arkl_syrweight : Data from syringe weights for iohex (Karonga / Lilongwe)
