Clinical and Polysomnographic Correlates of Subjective Sleepiness in Mild Obstructive Sleep Apnea.
Article in Sleep and vigilance, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
purposeThe decision to treat mild obstructive sleep apnea (OSA) often hinges on the presence of subjective daytime sleepiness. This study was done to identify clinical and polysomnographic features which correlate with subjective sleepiness in mild OSA.
methodsUtilizing data from the Apnea Positive Pressure Long-term Efficacy Study, 199 participants with mild OSA were identified. Participants were grouped as "sleepy" or "non-sleepy" based on their responses to a question regarding excessive daytime sleepiness, and Epworth Sleepiness Scores. We compared demographic, clinical and baseline polysomnographic data between the groups.
resultsThe prevalence of subjective sleepiness was 74.4%. The sleepy group was younger (46.1 ± 12.6 vs. 53.3 ± 13.1 years, p=0.001), reported lower quality of life (4.5 ± 0.69 vs. 4.9 ± 0.61, p=0.0002), had higher depression scores (5.4 ± 4.7 vs. 3.1 ± 3.5, p=0.003) and reported more naps per week (2.6 ± 2.9 vs. 1.3 ± 1.9, p=0.01). Total sleep time and sleep efficiency were notably higher in the sleepy (254.2 ± 106 vs. 220.4 ± 114 min, p=0.08) and (80.2 ± 12.6 vs. 75.7 ± 14.9 %, p=0.06), approaching statistical significance. The non-sleepy group had slightly higher apnea hypopnea index (AHI: 12.2 ± 1.5 vs. 11.2 ± 2.4 events/hour, p=0.01) and worse desaturation indices.
conclusionsSubjective sleepiness in mild OSA is associated with younger age, worsened mood and quality of life. This study suggests that evidence of increased sleep drive on polysomnography may correlate with subjective sleepiness in mild OSA.
