Table 1. Independent and conditional analyses of the coverage of the dimensions of antenatal care among pregnant women in a national retrospective study, Mexico, 2012.

Dimension of antenatal carea	% (95% CI)
	Independent coverage	Conditional coverage
Skilled	98.4 (98.1 to 98.8)	98.4 (98.1 to 98.8)
Timely	83.2 (81.8 to 84.6)	83.2 (81.8 to 84.6)
Sufficient	91.4 (90.3 to 92.5)	79.9 (78.4 to 81.4)
Appropriate	84.7 (83.3 to 86.2)	71.5 (69.7 to 73.2)

CI: confidence interval.

^a Skilled (antenatal care provided by a nurse or a physician); timely (initial antenatal care visit during first trimester of pregnancy); sufficient (≥ 4 antenatal care visits during pregnancy); appropriate (visits included at least 7/8 of recommended basic care procedures: measurement of height, weight, and blood pressure, urine analysis, blood examination, tetanus vaccine, and prescription of folic acid as well as vitamin/iron/food supplements.

Note: Sample n = 6494; sample weighted to population n = 9 052 044. Independent coverage was the percentage of the population receiving an intervention, measuring the coverage of each indicator separately. Conditional coverage refers to full compliance with antenatal care indicators, measuring the coverage of each indicator conditional on the coverage of the previous one.
