Timasamala U5 data

Data collected as part of a cross-sectional interferon-gamma release assay (IGRA) survey of healthy children, aged 1 to 4 years living in 33 high-burden neighbourhoods in Blantyre, Malawi. Participants were recruited through a combination of a novel convenience sampling approach in health facilities and random household sampling guided by satellite imagery. They were subsequently tested for Mycobacterium tuberculosis (Mtb) immunoreactivity using QFT-Plus IGRA. The files provided include a cleaned dataset covering participants with a QFT-Plus result, an R Markdown script written to perform the analyses, and accompanying data documentation. These were used to generate the analyses outlined in "Heterogeneity in Mycobacterium tuberculosis immunoreactivity in young children in Blantyre, Malawi: a community-based survey".
