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

objectivesThe presence of pleural adhesions during lung cancer surgery can obstruct the surgical field and inhibit maneuverability, thereby potentially complicating the procedure. The current study examined the potential predictive factors of pleural adhesions using standard preoperative examinations for lung cancer surgery without additional assessments.

methodsThis study included 542 patients with primary lung cancer who underwent chest computed tomography scan and positron emission tomography before undergoing surgery between January 2021 and September 2024. To assess differences in lung expansion between inspiration and natural breathing, the ratio of lung computed tomography scan measurements obtained during maximal inspiration-to-lung positron emission tomography measurements during spontaneous breathing was calculated. The ratios were compared between patients with pleural adhesions and those without.

resultsIn total, 56 patients were classified under the adhesion group and 486 under the non-adhesion group. If the ratio of the distance from the lung base to the interlobar fissure, measured on coronal computed tomography scan and positron emission tomography, was ≤ 1.390, and the angle of the lung base, measured on sagittal computed tomography scan, was ≥ 40°, the incidence of pleural adhesions was significantly higher (24.0% vs. 4.7%; p < 0.01).

conclusionStandard preoperative examinations could be effective in predicting pleural adhesion.
