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

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

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
  1. OR = odds ratio, CI = confidence interval.
  2. *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).
  3. † 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.
