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 effect of the number of negative lymph nodes (NLNs) removed on the overall survival (OS) and recurrence rate of ovarian cancer (OC) patients has not been investigated. This study aimed to investigate the effect of the number of NLNs removed on OC patients' survival and recurrence rate after primary surgery. In this multi-center cohort study, the medical profile of 504 OC patients (mean age 55.21 years and mean follow-up 78.5 ± 28.4 months) who underwent primary surgery between 2011 and 2021 in gynecological tumor surgery centers affiliated with Iran and Shahid Beheshti Universities of Medical Sciences, Tehran, Iran, was retrospectively examined. Based on the number of NLNs removed, patients were divided into four groups, including 0-9, 10-19, 20-30, and > 30 NLNs, including 152, 169, 124, and 59 OC patients, respectively. The 5-year survival was 49.1%. The median survival was 61 months. The RFS and OS were significantly better in patients with more than 30 NLNs removed compared to other groups. The multivariable analysis showed that the OS rate was significantly better in patients with the number of NLNs removed ≥ 20 compared to < 20 (HR, 1.88; 95% CI 1.15-2.62;
