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

backgroundAlthough sublobar resection (wedge resection [Wed] or segmentectomy [Seg]) has become a standard operative procedure for clinical stages IA1 and IA2 non-small cell lung cancer (NSCLC) in Japan, the impact of this procedure on the prognosis and postoperative complications in real-world clinical practice is unknown.

methodsThis study retrospectively analyzed risk factors for a poor prognosis and postoperative complications of 470 patients with clinical stage ≤ IA2 NSCLC who underwent surgery from 2012 to 2021.

resultsAmong the patients with a consolidation-to-tumor ratio (CTR) higher than 0.5, the 5-year relapse-free survival (RFS) rate was significantly lower in the Wed group (72.1%) than in the Seg (85.8%) and Lob (86.8%) groups (p < 0.01), but the difference between the Seg and Lob groups was not significant. Among patients with a CTR of 0.5 or lower, the 5-year RFS rate did not differ significantly among the three groups. Multivariable analysis of RFS showed that the prognosis was significantly worse in the Wed group than in the Lob group (hazard ratio, 2.83; p < 0.01), but the difference between the Wed and Seg groups or the between Seg and Lob groups was not significant. Multivariable analysis of postoperative complications showed a significantly lower risk in the Wed group than in the Seg group (odds ratio, 0.31; p < 0.01).

conclusionsSeg could become the standard operative procedure for clinical stages IA1 and IA2 NSCLC patients. Wed is suggested to be an option for patients with a CTR of 0.5 or lower and has the advantage of avoiding postoperative complications.
