Health-Related Quality of Life 24-36 Months After Vaginal Delivery with and Without Obstetric Anal Sphincter Injury: A Comparative Cohort Study.
Article in International urogynecology journal, 2026. 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
introduction and hypothesisObstetric anal sphincter injury (OASI) is associated with pelvic floor dysfunction and long-term morbidity; however, its independent impact on global health-related quality of life (HRQoL) remains uncertain. We hypothesized that women with OASI would have a higher probability of impaired HRQoL than women without severe perineal trauma.
methodsWe conducted a retrospective comparative cohort study at a tertiary referral center in Cali, Colombia. All women with documented OASI grade III-IV identified from the institutional delivery registry (n = 60) were compared with randomly selected women without OASI from the same source population and time period (n = 60; 1:1 ratio). HRQoL was assessed 24-36 months postpartum using the validated Spanish version of the Short Form Health Survey questionnaire. Impaired HRQoL was defined as a Physical Component Summary (PCS) or Mental Component Summary (MCS) score below 50. Adjusted odds ratios (OR) with 95% confidence intervals (CI) were estimated using multivariable logistic regression.
resultsAmong the 120 women included, mean PCS and MCS scores were 47.6 ± 7.7 and 44.5 ± 9.3 respectively. In adjusted analyses, OASI was not independently associated with impaired physical HRQoL (adjusted OR 1.94, 95% CI 0.87-4.43) or impaired mental HRQoL (adjusted OR 1.54, 95% CI 0.64-3.73). Mestiza ethnicity was independently associated with impaired mental HRQoL (adjusted OR 4.68, 95% CI 1.47-16.60).
conclusionsIn women evaluated 24-36 months after vaginal delivery, OASI was not independently associated with impaired physical or mental HRQoL. Broader social and contextual determinants appear to influence long-term postpartum quality of life more strongly than the perineal injury itself.
