Anthropometric indices of Gambian children after one or three annual rounds of mass drug administration with azithromycin for trachoma control

Table 2 Comparison of outcome measures in all children aged 1 to 4 years in annual MDA versus single MDA trial arms

Outcome	Annual MDA N = 1431	Single MDA N = 1455	Adjusted* coefficient (95% CI), p-value
WHZ, mean (SD)	-0.60 (1.01)	-0.60 (1.06)	-0.02 (-0.10 to 0.06), 0.651
HAZ, mean (SD)	-1.28 (1.13)	-1.35 (1.21)	-0.07 (-0.19 to 0.05), 0.257
WAZ, mean (SD)	-1.11 (0.96)	-1.15 (1.00)	-0.05 (-0.14 to 0.04), 0.264
			Adjusted† OR (95% CI), p-value
Wasted, n (%)	114 (8.0)	120 (8.3)	1.07 (0.81 to 1.40), 0.642
Stunted, n (%)	343 (24.0)	371 (25.5)	1.12 (0.90 to 1.41), 0.303
Underweight, n (%)	242 (16.9)	264 (18.1)	1.10 (0.89 to 1.37), 0.380

OR = odds ratio, CI = confidence interval.
*adjusted for between-household variation, between-EA variation, latrine access, time to water and district. P-values are from likelihood ratio tests comparing adjusted models with and without trial arm (annual MDA versus single MDA).
† adjusted for between-household variation and between-cluster variation as appropriate and a priori for latrine access, time to water and district. P-values are from likelihood ratio tests comparing adjusted models with and without arm.
