Graded and threshold effects of body mass index on perioperative outcomes after pancreaticoduodenectomy: a meta-analysis incorporating an institutional cohort.
Article in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Background: The influence of body mass index (BMI) on perioperative results after pancreaticoduodenectomy (PD) remains controversial. This study aimed to clarify how different BMI strata influence operative complexity, postoperative morbidity, and mortality. Methods: We performed a meta-analysis and systematic review of 25 studies, including one institutional cohort, evaluating BMI-related perioperative and survival outcomes in patients undergoing PD. The outcomes assessed included operative time, estimated blood loss, postoperative complications, clinically relevant pancreatic fistula, reoperation, perioperative mortality, and overall survival. Results: BMI ≥25 kg/m Conclusions: Overweight (BMI ≥25 kg/m
