Sex-Based Differences in Survival Among Patients with Acute Abdomen Undergoing Surgery in Malawi: A Propensity Weighted Analysis.
Article in World journal of surgery, 2023. 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
introductionSex disparities in access to health care in low-resource settings have been demonstrated. Still, there has been little research on the effect of sex on postoperative outcomes. We evaluated the relationship between sex and mortality after emergency abdominal surgery.
methodsWe performed a retrospective cohort study using the acute care surgery database at Kamuzu Central Hospital (KCH) in Malawi. We included patients who underwent emergency abdominal surgery between 2013 and 2021. We created a propensity score weighted Cox proportional hazards model to assess the relationship between sex and inpatient survival.
resultsWe included 2052 patients in the study, and 76% were males. The most common admission diagnosis in both groups was bowel obstruction. Females had a higher admission shock index than males (0.91 vs. 0.81, p < 0.001) and a longer delay from admission until surgery (1.47 vs. 0.79 days, p < 0.001). Females and males had similar crude postoperative mortality (16.3% vs. 15.3%, p = 0.621). The final Cox proportional hazards regression model was based on the propensity-weighted cohort. The mortality hazard ratio was 0.65 among females compared to males (95% CI 0.46-0.92, p = 0.014).
conclusionsOur results show a survival advantage among female patients undergoing emergency abdominal surgery despite sex-based disparities in access to surgical care that favors males. Further research is needed to understand the mechanisms underlying these findings.
