Diagnostic Accuracy and Educational Value of the RIPASA Score in Suspected Acute Appendicitis: A Prospective Study in an Emergency Department Training Setting.
Article in Advances in medical education and practice, 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
Background: Clinical scoring systems are increasingly used in emergency departments for decision support and risk stratification. This prospective observational study evaluated the diagnostic performance of the RIPASA score in suspected acute appendicitis and explored its potential role as a structured decision-support tool within a training environment. Methods: We conducted a prospective observational study in a university emergency department including patients aged ≥18 years presenting with suspected acute appendicitis. The RIPASA score was calculated during routine clinical assessment by physicians with varying levels of experience. Histopathological findings served as the reference standard for operated patients, while non-operated patients were followed for one month. Diagnostic performance was assessed using receiver operating characteristic analysis. Results: Among 135 included patients (median age 28 years), acute appendicitis was confirmed in 55 cases (40.7%). The RIPASA score demonstrated moderate diagnostic accuracy, with an area under the curve of 0.79 (95% CI, 0.72-0.87). The negative predictive value in the low-probability group reached 86.4%, whereas the positive predictive value in the high-probability group was 67.4%. Conclusion: The RIPASA score demonstrated moderate diagnostic performance for risk stratification in suspected acute appendicitis. While it may support structured clinical reasoning in training settings, it should not be used as a standalone tool for discharge decisions.
