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

Background: In the United States, histologic grade in non-small cell lung cancer (NSCLC) is not part of the TNM stage classification. We hypothesize that histologic grade may impact prognosis. Methods: The National Cancer Database (NCDB) for NSCLC was used to identify all pathological stage 1 cancer patients who underwent definitive surgery between 2013 and 2020. Three groups were created using histologic grade for both adenocarcinoma and squamous cell carcinoma: well-differentiated (G1), moderately differentiated (G2), and poorly/undifferentiated (G3). Results: The study cohort comprised 37,727 adenocarcinoma patients (10,784 G1, 18,647 G2, 8476 G3) and 17,697 squamous cell carcinoma patients (601 G1, 10,002 G2, 7904 G3) patients who underwent definitive surgical resection for stage 1 cancer. More patients in the G3 adenocarcinoma group had a larger tumor size (18 mm vs 20 mm vs 21 mm; Conclusions: Histologic grade for adenocarcinoma has gained international attention with the new classification scheme according to the International Association for Study of Lung Cancer. Histologic grade, at least in adenocarcinoma, may provide an important prognostic indicator, and further work is needed to tailor treatment for those with high-grade tumors.
