Fatigue-related factors and perceived team functioning in United States Navy Surface Forces.

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
Operational environments such as naval vessels demand sustained coordination and precision under conditions that test both physical and psychological endurance. This study examined associations among fatigue-related factors, perceived social support, occupational context, and perceived team functioning among 26 438 active-duty US Navy personnel. Measures included self-reported sleep needed, sleep opportunity, and sleep obtained, which were used to calculate sleep deficit and sleep opportunity conversion, along with self-reported sleep disturbance, fatigue impairment (FI), perceived social support, and perceived team processes. Hierarchical regression analyses showed that FI was strongly associated with lower perceived team functioning (β = -0.35; 95% confidence interval [CI], -0.37 to -0.33;
