* p < 0.05, ** p < 0.01, *** p < 0.001; Cluster robust standard errors employed; Municipalities grouped into priority or non-priority by programme allocation criteria and into five quintiles based on primary care doctor density prior to PMM implementation; Allocation priority and quintiles dummies interacted with dummy variable for PMM introduction to obtain effect sizes for each group from two separate regression models (priority and baseline quintiles) for each outcome; Adjusted for Health expenditure (R$) per capita, Private insurance plan coverage (%), Hospital beds per 1000 pop, GDP per capita, Bolsa Familia expenditure per poor person, Illiteracy rate (15 + year), Households with inadequate sanitation (%), Urbanisation rate (%), Income (R$) per capita, Households with no electricity (%), and state-year-quarter and municipal fixed effects; Doctor densities expressed per 100,000 population. Amenable mortality rate per 100,000 population aged under 75 years
