Prognostic Value of the Mannheim Peritonitis Index in Predicting Mortality Following Emergency Surgery for Hollow Viscus Perforation.
Article in Journal of emergencies, trauma, and shock. 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
Introduction: Perforation peritonitis is a life-threatening emergency associated with high morbidity and mortality. Early risk stratification is vital, particularly in resource-limited settings. The Mannheim peritonitis index (MPI) is a widely used prognostic tool, but its performance in Vietnamese patients remains underexplored. The objective of this study was to evaluate the prognostic accuracy of MPI in predicting inhospital mortality among patients undergoing surgery for secondary peritonitis due to hollow viscus perforation. Methods: This prospective observational study included 176 patients treated at a tertiary care center in southern Vietnam from April 2023 to May 2024. Clinical data were collected to calculate MPI scores. Mortality outcomes were analyzed using the receiver-operating characteristic curve and multivariate logistic regression. Results: The mean patient age was 64.9 ± 15.7 years; 70.5% were male. Generalized peritonitis occurred in 96%, and feculent contamination in 5.1%. The most frequent perforation sites were the stomach (43.8%) and duodenum (21%). Overall mortality was 21%. MPI demonstrated excellent predictive performance (area under the curve = 0.944; 95% confidence interval: 0.905-0.988; Conclusion: MPI is a reliable and efficient tool for early mortality prediction in secondary peritonitis. A threshold score ≥25 effectively identifies high-risk patients and should be integrated into clinical decision-making in emergency surgical settings.
