1 · What the graph read from it

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.

2 · The registry

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

introductionAcute appendicitis is a common abdominal emergency that often requires hospital care and urgent surgery. Diagnosis can be difficult, which sometimes results in unnecessary operations. To improve accuracy and reduce avoidable procedures, scoring systems, such as the Appendicitis Inflammatory Response (AIR) score, have been developed, using clinical features and inflammatory markers to guide risk stratification. This study evaluates the AIR score for its ability to distinguish between uncomplicated and complicated cases, rule out non‑appendicitis conditions, and reduce reliance on unnecessary admissions, imaging, and surgery.

methodsA prospective observational study was conducted at Kempegowda Institute of Medical Sciences and Research Centre, Bengaluru, India, including 100 patients aged ≥ 18 years presenting with right lower quadrant pain, suggestive of appendicitis. Patients were stratified into low, intermediate, and high-risk groups based on the AIR score. Management was tailored accordingly: low scores received outpatient follow‑up, intermediate scores were reassessed with possible imaging or laparoscopy, and high scores underwent immediate surgery. Outcomes included sensitivity, specificity, predictive values, and secondary measures such as negative appendectomy rate.

resultsAIR score ≥ 4 demonstrated sensitivity of 85.9%, specificity of 100%, PPV of 100%, and NPV of 80% (AUC: 0.94) for diagnosing appendicitis. AIR score ≥ 8 showed sensitivity of 85.7%, specificity of 97.6%, positive predictive value (PPV) of 94.7%, and negative predictive value (NPV) of 93.3% (AUC: 0.94) for complicated appendicitis. Negative appendectomy was significantly reduced when the AIR score was applied.

conclusionThe AIR score is a reliable diagnostic tool for appendicitis, outperforming traditional scoring systems. Its use can reduce unnecessary surgeries, hospital admissions, and imaging, thereby improving patient outcomes and resource utilization.
