To assess if being ‘non observed’ affected mortality, we performed a regression analysis only on Q2 and Q3 data in 2015, the same time period manual data were collected for the ‘non observed’ group. C-section was used as the reference variable, as it is the most commonly performed surgical procedure in low and middle income countries. Because there was no mortality reported at 24 hours in the ‘non observed’ group, we were unable to perform this analysis for 24-hour mortality. P-values <0.05 are indicated in bold.

^*N/W – night or weekend case.

Abbreviations: 95%CI – 95% confidence interval, C-section – Cesarean section, REF – reference value.
