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

backgroundVisceral pleural invasion (VPI) has been established as a significant prognostic factor in non-small cell lung cancer (NSCLC), which affects decisions on surgery method; however, there are currently no effective ways to confirm VPI in a timely manner. We hypothesized that visible pleural retraction (VPR) may correlate with VPI and share similar prognostic significance, thereby providing real-time guidance for surgical decision making. This study aimed to evaluate the prognostic value of VPR.

methodsThis retrospective cohort study included NSCLC patients with a tumor diameter ≤2 cm who underwent radical surgery. Survival analyses were performed to compare recurrence-free survival (RFS) and overall survival (OS) among patients with different VPI and VPR statuses. Multivariable Cox regression was conducted to identify independent risk factors for poor prognosis.

resultsOverall, 2033 patients were included, of whom 215 (10.6%) had VPI and 578 (28.4%) had VPR. The median follow-up time was 48.1 months. Patients with VPR had significantly worse RFS and OS compared with those without VPR (hazard ratio [HR] 4.91, 95% confidence interval [CI] 2.69-8.97, p < 0.001; and HR 7.44, 95% CI 3.35-16.55, p < 0.001, respectively). Among patients with VPR, there were no significant differences in RFS or OS based on the presence or absence of VPI (HR 0.99, 95% CI 0.44-2.22, p = 0.99; and HR 0.96, 95% CI 0.38-2.40, p = 0.90). Multivariate Cox regression analysis certified that VPR is an independent risk factor for both poor RFS and OS (HR 6.57, 95% CI 3.28-13.17, p < 0.001; and HR 8.817, 95% CI 3.51-22.16, p < 0.001, respectively).

conclusionsVPR is a reliable timely prognostic marker in T≤2cmN0M0 NSCLC, and the prognostic value of VPR is independent of VPI status.
