Epidemiology, presentation, and outcomes of sigmoid volvulus in malawi: an 11-Year retrospective review.
Article in BMC surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSigmoid volvulus (SV) is a significant gastrointestinal condition in sub-Saharan Africa, although its epidemiology and outcomes are poorly understood.
objectivesTo determine the prevalence, demographic characteristics, clinical presentation, and outcomes of SV in Malawi.
methodsAn 11-year retrospective review of patients with SV at Queen Elizabeth Central Hospital, Malawi. Patient records were analysed for demographic characteristics, clinical presentation, mode of management, and outcomes.
resultsWe identified 301 cases of SV, with a prevalence of 27.3 cases per year. Males comprised 91.4% of cases, with a mean age of 51. Emergency presentations accounted for 69.8% of cases. Resection and primary anastomosis were the most common surgical procedures. The mortality rate was 11.3%, with non-viability of bowel being a significant predictor of mortality.
conclusionsSV contributes significantly to the disease burden, particularly among middle-aged males seen in the surgical department. It presents acutely, and resection and primary anastomosis are the primary surgical approaches. Non-viability of bowel was identified as a significant predictor of mortality, emphasising the need for prompt surgical intervention.
