Sleep quality improvements and maintenance with exercise in older veterans with PTSD: Results from a pilot randomized trial.
Article in Mental health and physical activity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 and aims: Identifying novel strategies to improve sleep quality among individuals with post-traumatic stress disorder (PTSD) is critically needed. The aim of the study was to evaluate the effects of exercise on sleep quality in older adults with PTSD participating in a 12-week pilot randomized trial of supervised exercise versus waitlist control. Methods: This study is a secondary analysis of a randomized, two-group design comparing multicomponent exercise to a waitlist control. Results: Participants included 48 older Veterans with PTSD. The sample was, on average, 67.5 years old (SD = 3.6), primarily male (92%), and African American or Black (85%). At baseline, more than 90% of participants reported poor sleep quality. Linear models indicated medium effect size differences favoring the intervention group for PSQI global and daytime dysfunction (β's -0.31 to -0.40) and small effect size differences favoring the intervention group for PSQI sleep disturbance, sleep efficiency, sleep latency, sleep quality, and addendum for PTSD (βs -0.13 to -0.24). Within-group changes indicated small improvements in sleep quality in the exercise group (PSQI global, sleep disturbance, sleep duration, latency, quality; d's -0.11 to -0.26). In the control group, small deteriorations (PSQI global, sleep disturbance, daytime of dysfunction, use of sleep medications, sleep efficiency, sleep latency, PTSD sleep addendum) were found. There was no evidence of mediation in the exploratory mediation analysis evaluating the effect of PTSD symptom severity on the relationship between intervention condition (supervised exercise or control) and sleep quality. Conclusions: Findings provide preliminary evidence for exercise as a complementary intervention to maintain or improve sleep quality in this population.
