Annual Attributable Moderate-to-Severe Diarrhea Cases in Population and Incidence per 100 Child-Years in First 2 Years of the Global Enteric Multicenter Study: The Gambia, Ages 0–11 Months (312 Cases, 398 Controls)

Pathogen	AF	Annual Attributable Cases^a	Attributable Incidence Rate^b
Rotavirus	0.211	135	2.3
Cryptosporidium	0.095	61	1.0

M_SHC = No. of eligible MSD cases at SHCs (observed) = 625; r = proportion of MSD cases seen at SHC = 0.487; M_pop = annual MSD cases in population = M_SHC/(2r) = 642; N = No. of children in population = 5922.

Abbreviations: AF, attributable fraction; MSD, moderate-to-severe diarrhea; SHC, sentinel health center.

^a Calculated as AF × M_SHC/(2r).

^b Per 100 child-years; calculated as 100 × AF × M_SHC/(2rN).
