Relationship Between Body Mass Index and the Incidence of Perineal Tears in Primigravid Women: A Retrospective Cross-Sectional Study at a Hospital in Mexico.

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
introductionPerineal tears represent one of the main complications of vaginal delivery, with immediate and long-term consequences for maternal health. Although several factors have been associated with their occurrence, the role of maternal body mass index (BMI) remains controversial.
objectiveThis study aims to evaluate whether there is a significant difference in the incidence of perineal tears among primigravid women with different BMI categories.
methodsA retrospective cross-sectional study was conducted between March 2022 and February 2024 at the General Hospital of Specialties "Dr. Javier Buenfil Osorio" (Campeche, Mexico). A total of 180 (100%) primigravid women with term pregnancies were included and categorized according to BMI as normal weight, overweight, or obese. The incidence of perineal tears was compared among the groups.
resultsThe overall prevalence of perineal tears was 56.7% (102 patients). Tear rates were similar across BMI categories: normal weight with 58.3% (35 patients), overweight with 51.7% (31 patients), and obese with 60.0% (36 patients). No statistically significant differences were found (p = 0.622). Additionally, no correlation was identified using Kendall's Tau-b test (p = 0.854).
conclusionNo significant association was observed between maternal BMI and the incidence of perineal tears in primigravid women. Other obstetric factors may play a more relevant role.
