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

backgroundIncreasing surgeon age may influence patient outcomes after complex procedures due to gained experience but also decreased technical and cognitive abilities. This study aimed to clarify whether surgeon age influences patients' long-term survival after gastrectomy for gastric adenocarcinoma.

methodsPopulation-based cohort study including all patients who underwent open and curatively intended gastrectomy for gastric adenocarcinoma between 2006 and 2015 in Sweden, with follow-up throughout 2020. Surgeon age, categorized into three equal-sized groups (tertiles), was assessed in relation to 5-year all-cause mortality rate (main outcome) and 5-year disease-specific death (secondary outcome) using multivariable Cox regression adjusted for patient age, sex, education, co-morbidity, pathological tumour stage, tumour sublocation and neoadjuvant therapy. Lymph node yield, resection margin status, in-hospital complications and annual surgeon volume of gastrectomy were considered potential mediators.

resultsAmong 1647 patients, the 5-year all-cause mortality rate was increased for surgeon age ≥55 years (adjusted HR 1.21, 95% c.i. 1.04 to 1.41) and borderline elevated for age 47-54 years (HR 1.16, 95% c.i. 0.99 to 1.36), compared with age ≤46 years. Five-year disease-specific death was increased for surgeon age ≥55 years (HR 1.25, 95% c.i. 1.06 to 1.48) and 47-54 years (HR 1.22, 95% c.i. 1.02 to 1.44), compared with age ≤46 years. The associations attenuated and became statistically non-significant after adjustment for lymph node yield, resection margin status and complications.

conclusionSurgeon age ≥47 years might be associated with worse long-term survival in patients who undergo gastrectomy for gastric adenocarcinoma, possibly mediated in part by differences in lymph node yield, resection margin status and complications.
