Mortality rate and risk factors for relaparotomy after caesarean section: a systematic review and meta-analysis.
Synthesis in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe high prevalence of caesarean section (CS) is a global concern. Relaparotomy is needed when conservative managements are not effective in CS complications. This study aimed to systematically review and meta-analyze the mortality rate and risk factors of relaparotomy after CS.
methodsBased on a pre-registered protocol, we searched 11 databases. The MOOSE guideline was followed, and the reporting was in accordance with the PRISMA statement. A Freeman-Tukey double arcsine transformation was used to transform the raw data, and a random-effects meta-analytic model was applied. The quality of the evidence was evaluated by Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
resultsThe qualities of the pooled results were assessed to be "very low" based on the inclusion of observational studies. A total of 40 studies were retrieved. The mortality rate in patients after relaparotomy was 7.24% (95%CI 4.10-11.03%). Significant gap existed between high-resources and low-resources countries. In developed areas this rate was 0.56% and in places of low resources this rate was 16.90%. Higher CS rate correlated with higher mortality. Over 70% of the relaparotomies followed emergent CS. Risk factors associated with relaparotomy included higher maternal age, CS performed in the second stage of labor, twin pregnancy, preterm birth (OR 2.72, 95%CI 1.87-3.95) and preeclampsia (OR 3.24, 95%CI 1.47-7.14).
conclusionOur findings demonstrated the high mortality rate in patients who had relaparotomy after CS. Interpretation of the results should be with caution due to GRADE evidence level. During a time when there is an imbalance in medical resources in different countries, interventions to reduce CS rate, good prenatal care and intensified post-operative management are important.
