Insomnia Symptoms are Common Among Community Dwelling African Americans Who Report Poor Sleep.
Article in Behavioral sleep medicine, 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
objectivesAfrican Americans experience health disparities and notably report poorer sleep than their non-Hispanic White counterparts. This study aimed to identify behavioral and physiological contributors of self-reported poor sleep among African Americans.
methodEighty African Americans (50.1 ± 16.1 years [mean ± SD], 69 women) who reported poor sleep (<7 hr sleep/night, difficulty falling asleep or staying asleep, unrefreshing sleep, etc.) were enrolled. Sleep patterns were determined by 7-day accelerometry. Pittsburgh Sleep Quality Index (PSQI), Sleep Hygiene Index, Epworth Sleepiness Scale, and the Insomnia Severity Index (ISI) assessed sleep habits and disorders. Multidimensional Fatigue Inventory, Perceived Stress Scale, and Beck's Depression Inventory were also administered.
resultsParticipants self-reported poor sleep quality (PSQI, 9.63 ± 3.89) and insomnia symptoms (ISI, 14.4 ± 5.9); 45% of participants had clinically significant insomnia symptoms (ISI score > 15). Short sleep duration was common, with 72.5% of participants sleeping less than 6.5 hours/night. Sleep continuity was lacking (wake after sleep onset: 54.1 ± 30.4 minutes; sleep fragmentation index 29.0 ± 9.9%). High ISI scores were correlated with larger body mass index and worse scores for sleep quality, sleep hygiene, stress, daytime sleepiness, fatigue, and depression (
conclusionsInsomnia symptoms were common among our cohort of African Americans. Considering the relationships observed with ISI, treatment of insomnia may be targeted to reduce health disparities.
