Nutritional z scores in children ages 6–60 months in 24 communities randomized (1:1) to annual or biannual mass azithromycin treatment in a cluster-randomized clinical trial
| Metric | Annual treatment (12 communities) | Biannual treatment (12 communities) | Coefficient (95% CI)* | P value | ||
|---|---|---|---|---|---|---|
| N | Mean | N | Mean | |||
| WHZ | 481 | −0.89 ± 1.30 | 538 | −0.78 ± 1.08 | 0.09 (−0.16 to 0.34) | 0.48 |
| MUACZ | 483 | −1.25 ± 1.01 | 541 | −1.20 ± 0.93 | 0.03 (−0.18 to 0.23) | 0.81 |
| HAZ | 482 | −3.13 ± 2.24 | 541 | −3.07 ± 1.71 | 0.07 (−0.31 to 0.45) | 0.71 |
| WAZ | 483 | −2.44 ± 1.45 | 541 | −2.23 ± 1.24 | 0.12 (−0.15 to 0.39) | 0.38 |
Numbers may be different because of some loss during field examination, and z scores could not be calculated for children age 5 years at the time of anthropometry.
*
Mixed effects linear regression was used with community as a random effect; coefficient reflects the change in z score in the biannually treated arm relative to the annually treated arm.
