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

Objective: To analyze the characteristics and risk factors of postoperative pneumonia (POP) in emergency surgery at tertiary general hospitals, aiming to provide scientific evidence for early screening of high-risk populations and optimization of POP prevention strategies. Methods: A retrospective analysis was performed on POP data from emergency and elective surgery patients between 2015 and 2024. Infection characteristics were compared between the two groups. Results: Among 399,347 surgical patients, 2,478 (0.62%) developed POP. The incidence of POP was significantly higher in emergency surgery (2.28%) than in elective surgery (0.53%, Conclusion: Emergency surgery carries a significantly higher risk of POP than elective surgery. Special attention should be paid to patients undergoing neurosurgery, cardiovascular surgery, and thoracic surgery. For patients with identified risk factors, enhanced perioperative management and individualized preventive strategies are essential to reduce POP incidence and improve emergency surgery outcomes.
