Antepartum Risk Factors Associated with Cesarean Section (Controlled for Age, Parity, and Year of Delivery) in the SW Trifinio Population, 2015 – 2017

Condition	RR^a	Confidence Interval	P-Value
Prolonged/Obstructed Labor	3.6	2.9 – 4.5	<0.001
Transverse/Breech Presentation	2.6	2.2 – 3.2	<0.001
Any Antepartum Condition	5.6	4.3 – 7.4	<0.001
Prior Cesarean Section	4.8	3.4 – 6.9	<0.001

Bivariate poisson regression model with a robust error variance adjusting for age, parity and year of delivery was used to estimate the relative risks (RR), confidence intervals and p-values
