| Intervention (Kalomo) endline versus baseline | 4.71 (2.68 to 8.26) | 0.000 |
| Comparator (Monze) endline versus baseline | 0.72 (0.43 to 1.19) | 0.200 |
| Time by study-arm interaction | 6.55 (2.96 to 14.49) | 0.000 |
| Intervention (Katete) versus comparator (Petauke) at baseline | 1.06 (0.74 to 1.52) | 0.749 |
| Intervention (Katete) versus comparator (Petauke) at endline | 1.57 (0.78 to 3.15) | 0.208 |
