Factors influencing pregnant women's use of antenatal and emergency care services covered by social security: findings from the maternal eCohort in Mexico.
Observational study in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEvidence on antenatal care (ANC) and emergency service utilization during pregnancy in Latin America remains limited. Understanding these patterns is critical given the substantial benefits of ANC and emergency services in improving maternal and neonatal outcomes, preventing and managing pregnancy complications, and reducing maternal and infant mortality. This study examined ANC and emergency service utilization among pregnant women affiliated with the Mexican Institute of Social Security (IMSS) and identified factors associated with their use.
methodsWe conducted an observational eCohort study through telephone interviews with 1,390 pregnant women aged 18-49 who initiated ANC at IMSS. Outcomes included the number of ANC visits, emergency room use, perceived quality of ANC, and provider competence assessed through 12 recommended ANC activities: blood pressure and weight measurement, blood and urine tests, ultrasound, and counseling on nutrition, warning signs, birth preparedness, newborn care, psychological health, and folic acid and iron supplementation. Multivariable negative binomial regression models were used to identify factors associated with ANC attendance and emergency service use.
resultsOf the full cohort, 3.7% exited due to miscarriage, 12.4% dropped out after baseline, and 11.8% dropped out during follow-up. One-third of women who left rated the quality of their first ANC visit as poor or fair. In addition, 30% of women who remained in the cohort reported poor or fair ANC quality. On average, participants reported six ANC visits, with 64.8% receiving at least 80% of the 12 recommended ANC activities. Nearly 30% sought emergency services during pregnancy. Higher ANC attendance was associated with hypertension, urinary infections, anemia, early ANC initiation, consultations with obstetricians, and hospital-based ANC follow-ups. Use of emergency services was more common among women with chronic diseases, hypertensive disorders of pregnancy, urinary tract infections, risk of miscarriage, or risk of depression.
conclusionsSubstantial improvements in ANC are needed to strengthen women's care experiences and promote consistent utilization of ANC services.
