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

backgroundWhile the long-term survival rate among patients with pancreatic and periampullary carcinomas remains low, it can be influenced by various factors. The purpose of this retrospective study was to investigate the effects of body mass index (BMI) on postoperative complications and patient survival after pancreatic resections for underlying malignancy over a 20-year observation period.

methodsWe analyzed 1,384 patients, 918 patients with pancreatic ductal adenocarcinoma (PDAC) (66.3%), 229 patients with distal cholangiocarcinoma (16.5%), 206 ampullary carcinoma patients (14.8%), and 31 duodenal carcinoma patients (2.2%). Patients were classified into four groups (group 1 <18.5; group 2, 18.5-25.0; group 3, 25.1-30.0; group 4 >30.0) according to their BMI (kg/m

resultsWithin a mean observation period of 687.7 [2-8,500] days, 735 (53.1%) patients died. There were important differences in postoperative complications (group 1, 16.2%; group 2, 20.3%; group 3, 27.2%, group 4, 41.6%) with the type of postoperative complications also varying between the groups. Overall 1-, 5-, 10- and 15-year survival rates were 66.4%, 25.5%, 17.9%, and 12.1%, respectively, with survival rates varying amongst the four groups.

conclusionsPatients with a BMI between 18.5 and 30 show better postoperative outcomes, regarding complications, hospitalization duration, and reoperation rates than underweight or obese patients. Short-term survival depends strongly on postoperative complications while patients with a higher BMI show better long-term survival rates.
