Predictors of Infection after Cesarean Delivery.
Trial report in American journal of perinatology, 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
Objective: Postoperative infections remain a significant complication of cesarean delivery (CD), with rates ranging from 3 to 30%. These infections increase healthcare costs, prolong recovery, and negatively impact maternal outcomes. Identifying risk factors for infection might help guide preventative strategies to mitigate this burden. The primary aim of this study was to develop and validate a predictive model for infection after CD using preoperative and perioperative characteristics. Study Design: This study was a secondary analysis of a multicenter randomized trial comparing tranexamic acid versus placebo to prevent postpartum hemorrhage in individuals undergoing either scheduled or unscheduled CD. The primary outcome of this analysis was a composite of surgical site infection, endometritis, or pelvic abscess diagnosed within 6 weeks postpartum. Univariable and multivariable bootstrapped logistic regression models with stepwise selection were used to identify predictors of infection. Model performance was evaluated using the receiver operator curve area under the curve (AUC). Results: Of the 10,995 participants, 287 (2.6%) developed an infection. Significant predictors included tobacco use (OR: 1.67, 95% CI: 1.21-2.31), BMI at delivery ≥ 30 kg/m Conclusion: Multiple modifiable and nonmodifiable factors influence infection after CD. This predictive model offers a framework for assessing individualized risk, though its modest performance indicates that further refinement is necessary before it can be confidently applied in clinical decision-making. Future research should aim to enhance predictive accuracy and explore whether risk stratification meaningfully informs prevention or patient counseling strategies. Key Points: · This study aimed to create a model to predict postpartum infection after cesarean delivery.. · Several factors were linked to higher infection risk after cesarean delivery. These included tobacco use, obesity, labor before cesarean, longer surgery, uterine incision extension, and uterotonic use.. · The model had moderate accuracy, with an AUC of 0.6.. · Common perioperative factors may help predict infection risk after cesarean delivery..
