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

backgroundIndocyanine green-guided (ICG-guided) lymphadenectomy during gastrectomy for cancer has been proposed to enhance the accuracy of lymphadenectomy. The impact of ICG-guided lymphadenectomy on patient survival remains debated.

methodsThe findings of the systematic review were reconstructed into an individual patient data (IDP) meta-analysis with restricted mean survival time difference (RMSTD). Overall survival (OS) and disease-free (DFS) survival were primary outcomes. RMSTD, standardized mead difference (SMD), and 95% confidence intervals (CI) were used as pooled effect size measures.

resultsThree studies (6325 patients) were included; 42% of patients underwent ICG-guided lymphadenectomy. The patients' age ranged from 47 to 72 years and 58% were males. Proximal, distal, and total gastrectomy were completed in 6.8%, 80.4%, and 12.8% of patients, respectively. The surgical approach was laparoscopic (62.3%) and robotic (37.7%). ICG-guided lymphadenectomy was associated with a higher number of harvested lymph nodes compared to non-ICG-guided lymphadenectomy (SMD 0.50; 95% CI 0.45-0.55). At the 42-month follow-up, OS and DFS estimates for ICG-guided vs. non-ICG-guided lymphadenectomy were 0.5 months (95% CI -0.01, 1.1) and 1.3 months (95% CI 0.39, 2.15), respectively.

conclusionsOur analysis suggests that ICG-guided lymphadenectomy offers equivalent long-term OS and DFS compared to non-ICG-guided lymphadenectomy.
