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

introductionThe conflicting impact of obesity on pulmonary function has been observed. Our study aimed at exploring the relationship between body mass index (BMI) and pulmonary function parameters in individuals with obesity.

methodsThis cross-sectional study included a consecutive cohort of bariatric surgery candidates with pulmonary function tests. BMI, analyzed as both quartile-stratified groups and a continuous variable, was evaluated for associations with pulmonary function parameters and the risk of pulmonary impairment.

resultsA total of 1,834 patients with obesity (BMI range: 27.5-76.4 kg/m2) were included in our study. BMI exhibited a significantly positive correlation with forced vital capacity (FVC), forced expiratory volume in 1 s (FEV

conclusionBMI exhibited a nonlinear relationship with pulmonary function parameters. Beyond the critical threshold of 38.2 kg/m2, increasing BMI led to a significant decline in ventilatory capacity, concomitant with an amplified risk of pulmonary function impairment.
