POWER CALCULATIONS The investigators powered the existing study to ensure that they could detect a 0.1 standard deviation (25%) change in the primary outcome, hospitalization, and a 1/3 standard deviation (26.5%) change in secondary outcome, financial status as proxied by a composite measure of asset levels drawn from the Indian National Sample Survey (NSS) survey. The investigators also padded the sample to allow for 10% attrition. The power calculations required each group have roughly 2,250 households. The large sample size requirement is driven primarily by the rarity of the hospitalization, roughly 2.5 per 100 persons per year in Karnataka.
