Single Catheterization for Preventing Postpartum Urinary Retention in Early Postpartum Voiding Failure: A Propensity Score-Based Study.

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 hypothesisEvidence on single postpartum catheterization for preventing postpartum urinary retention (PUR) remains limited. We aimed to investigate the effectiveness of postpartum single catheterization in preventing PUR among parturients with early voiding failure (bladder volume ≥ 300 mL and inability to void spontaneously).
methodsThis retrospective cohort study used real-world data. Participants were allocated to the single catheterization group or non-catheterization group. Primary outcomes were PUR and need for indwelling catheterization. PUR was further analyzed according to its two subtypes: overt PUR and covert PUR. Secondary outcomes included spontaneous voiding and number of induced voiding attempts. Stabilized inverse probability of treatment weighting (sIPTW) adjusted for confounders. Subgroup and sensitivity analyses were performed.
resultsOf 1637 screened parturients, 1316 were included (measurements within 3 h postpartum). Catheterized group 776 (59.0%); non-catheterized 540 (41.0%). After sIPTW, single catheterization was associated with lower risks of PUR (OR 0.47, 95% CI 0.36-0.61) and covert PUR (OR 0.40, 95% CI 0.30-0.53, P < 0.001), but not with overt PUR, indwelling catheterization, spontaneous voiding, or number of induced voiding attempts (P > 0.05). In a secondary analysis restricted to 2 h postpartum, single catheterization was associated with lower risks of PUR, covert PUR, indwelling catheterization (OR 0.57), and fewer induced voiding attempts (OR 0.79, P < 0.05), but not with overt PUR or spontaneous voiding.
conclusionsIn parturients with early voiding failure, single catheterization within 3 h postpartum was associated with reduced PUR and covert PUR risk. Within 2 h, it was additionally associated with lower indwelling catheterization risk and fewer induced voiding attempts. These observational findings require prospective validation.
