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

backgroundTo investigate the relationship between preoperative diaphragmatic dome height (DDH), measured on chest radiographs, and postoperative overall survival (OS) and disease-specific survival (DSS) due to respiratory-related deaths in patients with lung cancer and obstructive ventilatory disorder (OVD).

methodsThis single-center retrospective study included 302 patients with lung cancer and OVD who underwent lobectomy between 2017 and 2024. DDH was measured on chest radiographs 1 month preoperatively, and the patients were divided into the low DDH (lower than the first quartile, 18.8 mm) and high DDH (≥ 18.8 mm) groups. The associations of DDH with OS and DSS were evaluated using Cox proportional hazards models and Fine-Gray competing risk analysis, respectively. Kaplan-Meier curves and log-rank tests were used for survival comparisons.

resultsOverall, 65 patients (21%) died postoperatively. Cox proportional hazards and Fine-Gray analyses indicated that DDH (hazard ratio: 2.10, 95% confidence interval [CI]: 1.22-3.61, p < 0.01; subdistribution hazard ratio: 2.50, 95% CI: 1.14-5.45, p < 0.05) was an independent prognostic factor for 3-year OS and DSS. Furthermore, survival curve analysis demonstrated that the low DDH group had significantly lower 3-year OS (70% vs 85%, p < 0.01) and 3-year DSS (80% vs 92%, p < 0.01) compared with the high DDH group.

conclusionsDDH is an independent prognostic factor for OS and DSS in patients with lung cancer and OVD, suggesting that it can serve as a novel physiological marker for long-term prognosis.
