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

The prognostic value of 4L lymph node dissection (4L-LND) continues to be controversial. We conducted this systematic review and meta-analysis to evaluate the prognosis of 4L-LND in operable non-small-cell lung cancer (NSCLC) patients. We systematically searched studies from PubMed, Embase, and the Cochrane Library up to May 1, 2023. Studies investigating the prognostic value of 4L-LND and non-4L-LND in NSCLC survival were included. Data for analysis mainly comprised postoperative complications, overall survival (OS), and disease-free survival (DFS). The Q-test and I
