Control variables
ANTEPARTUM HAEMORRHAGE, PRE-ECLAMPSIA, COMPLICATIONS, SECONDARY
Since the QI measures were based on the subjective report of the respondents, the effect of the personal characteristics of the respondents, which differed significantly between sites, was adjusted. These included age, the highest level of education, religion, occupation, and diagnosis of complications such as antepartum haemorrhage, and pre-eclampsia, among others. Age was in single years, but for the descriptive purpose, it was re- categorised into five-year groups except the last category (40–49) because of few cases in this bracket. The highest level of education was categorized as no formal education, primary, secondary and higher. Religion was categorized as Catholic, Other Christian, and Islam. The occupation of the respondents was grouped into not working, civil servant (government employee), self-employed, and private sector employee.
