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
IntroductionCurrent research mainly examines the link between sarcopenia and obstructive spirometry, with limited studies on preserved ratio impaired lung function (PRISm). This study aims to investigate the association between skeletal muscle index (SMI) and lung function indicators in populations with different characteristics, with particular emphasis on the PRISm population.MethodsData were utilized from the National Health and Nutrition Examination Survey (NHANES) 2011-2012 cycle. The participants were categorized into three groups: obstructive spirometry, PRISm, and normal spirometry. The SMI was calculated by dividing appendicular skeletal muscle mass by body mass index. Multiple linear regression analysis was employed to explore the relationship between the SMI and lung function indicators, including forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC).ResultsAmong the 2513 participants aged 20-59 years, 2096 had normal spirometry, 186 were in the obstructive spirometry group, and 231 were in the PRISm group. The SMI was significantly associated with lung function indicators after adujustment: in the obstructive spirometry group, per 0.1 unit increase in SMI was linked to an increase in FEV1 of 0.214 L (95% CI: 0.115-0.313,
