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

BACKGROUND Obesity contributes to chronic kidney disease (CKD) through various mechanisms and increase morbidity and mortality after kidney transplantation. Bariatric surgery can reduce perioperative risks. This study aimed to determine the prevalence of obesity in kidney transplant candidates, associations with demographic and clinical factors, and to estimate the proportion of patients potentially eligible for bariatric surgery in a German cohort. MATERIAL AND METHODS This retrospective single-center study included 275 patients listed for kidney transplantation between November 2018 and January 2020 at the University Hospital Frankfurt. Prevalence analyses were limited to 271 patients. Variables included body mass index (BMI), comorbidities, cause of kidney disease, dialysis duration, transplant list status, and prior bariatric surgery. The primary endpoint was the prevalence of obesity; secondary endpoints were correlations between obesity and comorbidities. Statistical analyses included Spearman's correlation and Eta coefficient analyses to evaluate associations. Prevalence estimates are reported with 95% confidence intervals. RESULTS The mean BMI was 25.8 kg/m². BMI correlated with arterial hypertension (η=0.121; P=0.047) and diabetes mellitus (η=0.305; P<0.001), while no significant correlation was observed with transplant list status (η=0.051; P=0.704). Among the 56 obese patients, 6 (10.7%) had BMI 35-39.9 kg/m² and 4 (7.1%) had BMI ≥40 kg/m², meeting common eligibility criteria for bariatric surgery. The prevalence of obesity was 20.7% (95% CI, 1.16-1.25). CONCLUSIONS Obesity is prevalent in this population. Given that obesity is a modifiable risk factor, identifying candidates who may benefit from weight-management interventions is clinically relevant; however, this prevalence study does not allow conclusions regarding outcomes or treatment efficacy.
