Aortic regurgitation is associated with African American and Asian race, smoking, renal disease, and numerous autoimmune diseases in addition to traditional cardiovascular risk factors but has lower risk with alcohol intake.

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
backgroundAortic regurgitation (AR) is associated with increasing age, rheumatic heart disease, and a bicuspid aortic valve, but its association with other comorbidities and race is less known. The purpose of this study was to investigate any association between AR and comorbid conditions in older adults above 40.
methodThe large Nationwide Inpatient Sample database was utilized for our study using uni- and multivariate analysis. Data were extracted from available ICD-10 codes for the years of 2016-2020.
resultsThe NIS data included 112,982,565 patients. A total of 660,730 were found to have AR. AR was found to be associated with male gender (OR 1.15, CI 1.14-1.16, P < 0.001), smoking (OR 1.04, CI 1.02-1.05, P < 0.001), hypertension (OR 1.65, CI 1.62-1.68, P < 0.001), hyperlipidemia (OR 1.36, CI 1.34-1.37, P < 0.001), chronic kidney disease (OR 1.22, CI 1.21-1.24, P < 0.001), antiphospholipid antibody syndrome (OR 1.56, CI 1.33-1.83, P < 0.001), rheumatoid arthritis (OR 1.1, CI 1.06-1.14, P < 0.001), scleroderma (OR 1.49, CI 1.31-1.7, P < 0.001), systemic connective tissue disorders (OR 1.32, CI 1.25-1.4, P < 0.001), Raynaud's syndrome (OR 1.62, CI 1.47-1.77, P < 0.001), and systemic lupus erythematosus (OR 1.44, CI 1.34-1.54, P < 0.001) in add to known bicuspid aortic valve.
conclusionUsing a very large database, we found new associations between AR and many comorbid conditions, including many inflammatory and chronic degenerative diseases in addition to the known risk factors.
