Table 3. Child height growth velocity from baseline to 60−72 months.
| Time-point | Control (n = 128) | Intervention (n = 166) | Mean difference (95% CI)a | P-valueb |
|---|---|---|---|---|
| 12−16 months | 12.66 (10.58−14.74) | 12.41 (10.38−14.44) | 0.25 (−2.16−2.66) | 0.81 |
| 20−24 months | 10.70 (9.17−12.22) | 11.27 (9.78−12.77) | −0.58 (−2.35−1.20) | 0.40 |
| 36 months | 8.95 (8.27−9.62) | 9.41 (8.74−10.08) | −0.46 (−1.25−0.33) | 0.14 |
| 60−72 months | 7.78 (7.37−8.19) | 7.84 (7.44−8.24) | −0.06 (−0.54−0.42) | 0.71 |
We calculated the difference between height at each time-point (12−16, 20−24, 36 and 60−72 months) and baseline height values divided by the follow-up time. The obtained values are given as cm/year and presented as mean (95% confidence interval).
a
Mean difference is the cluster-adjusted difference in means between the control and intervention and group.
b
P-values from multilevel regression models with the cluster as random intercept. CI, confidence interval.
