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) represents a significant complication in lung cancer (LC) patients following lung resection, contributing to poor outcomes. This systematic review and meta-analysis aimed to identify clinical predictors and outcomes of POP in LC. A systematic search was conducted in EBSCOhost, Embase, PubMed/MEDLINE, Scopus, and Web of Science, with screening and reporting following preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Meta-analyses were performed in Jamovi 2.3.28, reporting results as odds ratios (OR) or standardised mean differences (SMD). Egger's test and Fail-safe N were used to assess publication bias and evidence robustness (PROSPERO: CRD42024551104). A total of 17 studies encompassing 21,104 LC patients (1,610 with POP and 19,494 without) were included. Reduced FEV1 (SMD: -0.48, 95%CI: [- 0.61, -0.36], P < 0.001) predicted POP. Surgical predictors of POP included VATS (OR: 0.575, 95%CI: [0.448, 0.737], P < 0.001), segmentectomy (OR: 0.459, 95%CI: [0.261, 0.805], P = 0.007), wedge resection (OR: 1.828, 95%CI: [1.189, 2.809], P = 0.006), lobectomy (OR: 0.626, 95%CI: [0.488, 0.803], P < 0.001), bilobectomy (OR: 2.367, 95%CI: [1.408, 3.979], P = 0.001), and pneumonectomy (OR: 1.750, 95%CI: [1.178, 2.600], P = 0.006). Left lung tumours increased POP risk (OR: 1.254, 95%CI: [1.050, 1.499], P = 0.013), while right lung tumours were protective (OR: 0.801, 95%CI: [0.670, 0.975], P = 0.015). POP was associated with longer surgery (SMD: 0.22, 95% CI: [0.11, 0.34], P < 0.001), extended hospitalisation (SMD: 1.19, 95%CI: [1.07, 1.30], P < 0.001), and significantly higher overall mortality OR: 12.12, 95% CI: [5.540, 26.550], P < 0.001). POP in LC patients is influenced by respiratory function, surgical approach, and tumour location, and predicts poor survival, emphasising the need for preventive strategies.
