|---|---|---|---|---|---|
| Antigen | Community (N = 314) | Model 1: Community (N = 314) vs. all facility (N = 650) | Model 2: Community (N = 314) vs. all female facility (N = 476) | Model 3: Community (N = 314) vs. ANC attendees facility (N = 167) | Model 4: Community (N = 314) vs. male and non-antenatal care female patient facility (N = 483) |
| Measles | 94.9 (92.1, 97.6) | 0.01 | 0.01 | 0.07 | 0.005 |
| Rubella | 91.0 (87.2, 94.8) | 0.32 | 0.34 | 0.70 | 0.32 |
Note: Community represents survey-weighted estimates for all clusters in the post-SIA survey.

Logistic regression adjusted for age in years, with survey weights applied for community-based specimens. Models including both sex for residual specimens also adjusted for sex (Model 1 and Model 4). Bold indicates p-value < 0.006 (Bonferroni-adjusted p-value accounting for eight comparisons).
