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

Postoperative pneumonia (POP) is a prevalent and serious complication following thoracic surgery, substantially increasing morbidity, mortality, and healthcare expenditures. The aim of this study was to evaluate the efficacy of perioperative oral care (POC) in reducing the incidence of POP. A comprehensive literature search was conducted across the Cochrane Library, Web of Science, PubMed, and Embase from their inception through September 26, 2024. We included all observational studies and randomized controlled trials (RCTs) that assessed the impact of POC on POP reduction. A total of 25 studies, involving 52,227 patients (24,964 in the POC group and 27,263 in the control group), were included in the final analysis, comprising 9 RCTs and 16 observational studies. The incidence of POP was 2,887 cases (11.6%) in the POC group, compared with 3,438 cases (12.6%) in the control group. The meta-analysis revealed that POC was associated with a significantly reduced incidence of POP in patients undergoing thoracic surgery (RR, 0.54; 95% CI, 0.44-0.67; p < 0.001; I² = 72%). In conclusion, POC significantly reduces the incidence of POP in thoracic surgery patients, and its integration into perioperative protocols may improve clinical outcomes.
