Carotid Intima-Media Thickness, Overweight, and Poor Sleep Quality in Commercial Airline Pilots: A Cross-Sectional Study.

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
Background Cardiovascular disease is a leading cause of premature career termination in commercial airline pilots (APs). In this cross-sectional study, we sought to investigate the relationship between intima-media thickness (IMT), a marker of subclinical atherosclerosis, and cardiovascular risk factors in APs, focusing on overweight status and sleep quality. Methods A total of 140 male APs were categorized into four groups based on body mass index (BMI) and Pittsburgh Sleep Quality Index (PSQI) score: overweight poor sleepers (OW-PS), overweight good sleepers (OW-GS), normal weight poor sleepers (NW-PS), and normal weight good sleepers (NW-GS). IMT was quantified in the common carotid artery (CCA) and carotid bulb using ultrasound, yielding a composite IMT (IMTcom) measure. Common cardiovascular risk factors were assessed in all participants. Results The prevalence of overweight and poor sleep quality was 43.6% and 32.9%, respectively. The OW-PS group had significantly higher age, heart rate, total cholesterol, and low-density lipoprotein (LDL) cholesterol compared to other groups (p<0.05). Overweight pilots, regardless of sleep quality, had increased IMTcom compared to normal-weight pilots (p<0.001). Age and LDL cholesterol were independent predictors of IMTcom in the OW-PS and OW-GS groups (p<0.05). Conclusions Overweight status, irrespective of sleep quality, is associated with increased IMT in APs, suggesting a higher burden of subclinical atherosclerosis. Interventions focused on reducing LDL cholesterol levels and managing age-related cardiovascular risk factors could be advantageous in mitigating the risk of atherosclerotic vascular disease in overweight pilots.
