Table 3 Fixed effect regression models for adjusted associations between average BFP coverage of the last 1,2,5,10 and 11 years—divided in quartiles—and maternal mortality ratio in women < 30 years in the municipalities selected (n.2548) for the quality of vital information in Brazil 2004–2014. Models are adjusted for the same independent variables of Table 2

From: Long-term impact of a conditional cash transfer programme on maternal mortality: a nationwide analysis of Brazilian longitudinal data
