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

backgroundProcedural volume is an important determinant of outcomes in cancer surgery. There is a lack of a comprehensive and updated assessment of hospital and surgeon volumes in relation to short- and long-term outcomes after gastrectomy for cancer.

methodsThe PubMed and Embase databases were searched on January 2021. We conducted meta-analyses and meta-regressions assuming a random effects model to assess the associations of procedural volumes with outcomes after gastrectomy. Effect sizes included hazard ratios (HRs), odds ratios (ORs), and standardized mean differences (SMDs). Heterogeneity was evaluated with the I

resultsWe identified 53 primary publications on the effect of hospital (n = 48) or surgeon (n = 11) volume on 11 gastrectomy outcomes. Patients operated on in high-volume centers had better overall survival (HR 0.82, 95% confidence interval [CI] 0.75-0.90), lower short-term mortality (OR 0.66, 95% CI 0.58-0.75), more adequate lymphadenectomy (OR 2.14, 95% CI 1.76-2.59), and shorter length of stay (SMD - 0.08, 95% CI - 0.12 to - 0.04). The meta-analysis showed no significant associations of hospital volume with surgical complications, R0 or negative margin resection, or disease-free survival (all p > 0.05). A higher surgeon volume was associated with lower 30-day mortality (OR 0.94, 95% CI 0.90-0.97).

conclusionsThe current study suggested with high confidence that gastric cancer patients operated on in high-volume centers had better overall survival. Centralization of gastrectomy in high-volume centers might lead to an overall improvement in other outcomes, but more studies, especially on surgeon volume, are needed.
