Comparisons were made using Mixed-Effects Poisson Regression Model between centrality scores and likelihood of receiving a referral up the health system as calculated by the incidence rate ratio due to non-normal distribution of the dependent variable. Reference values are as follows: Sex, female; Years Worked, 0–1 year; Title, Clinical Officer; Facility Level, Health Centre + Dispensary. Statistical significance set at p < 0.05
