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

Portomesenteric vein thrombosis (PMVT) is a rare but potentially fatal complication of metabolic and bariatric surgery (MBS). This study aimed to describe the clinical presentation, management, and outcomes of PMVT in a large, international cohort of patients undergoing MBS. As a case-series without denominators, this study provides descriptive epidemiology rather than incidence estimates. In this cohort, higher BMI (OR 1.21) and diabetes mellitus (OR 12.06) were associated with increased mortality in an exploratory multivariable analysis; however, due to the small number of events (n = 11), these findings should be considered exploratory and hypothesis-generating. Abdominal pain was the most frequent symptom (87%). The superior mesenteric vein was the most affected vessel (68.8%). The overall mortality rate was 14.3%.

conclusionPMVT after MBS is a serious complication with significant mortality. A high index of suspicion is required for early diagnosis and management. In this cohort, higher BMI and diabetes mellitus were associated with mortality; however, these findings should be considered exploratory due to the small number of events. Further research is needed to optimize thromboprophylaxis protocols in high-risk patients.
