Figure 1.
The phenomena regarding the child nutrition were assumed to be homogenous among the districts of the study zone. Thus, four districts out of nine were selected using simple random sampling. The health facilities rendering OTP were stratified into health centers and health posts. One health center and three satellite health posts were included from each district. Using the Probability Proportional to Size (PPS), the n1, n2, n3, and n4 samples were drawn. Finally, the OTP record card of each child was selected using systematic random sampling. HP: health post; HC: health center.

Kaplan Meier survival curves and Log-rank test for recovery rates over grouped factors.
The KM survival curves for each grouped factor were identified by color and pattern differences. They showed the recovery rates over the OTP intervention. The KM curves enable to compare the recovery rates between those with and without diarrhea, vomiting, loss of appetite with Plumpy'Nut, failure to gain weight and over children who took de-worming and amoxicillin drugs as compared to those who didn't take the drugs. The log-rank tests the significance of the observed differences in recovery rates on the KM survival curves between the grouped factors. X2: Chi-squared test.
