1 · What the graph read from 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.

2 · The registry

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

Hypertension is one of the most common chronic cardiovascular diseases in adults while obstructive sleep apnea (OSA) is the most common type of sleep apnea. It was recently reported that the mean Epworth Sleepiness Scale (ESS) score, measuring subjective daytime sleepiness, was significantly higher in non-hypertensive subjects than the hypertensive counterparts with moderate to severe obstructive sleep apnea. In the current study, the authors investigated the interaction between hypertension and OSA on daytime sleepiness among 280 subjects recruited from a sleep study. OSA was evaluated with the Apnea-Hypopnea Index (AHI), and daytime sleepiness was measured with the ESS. Significantly higher mean ESS scores were found for subjects without than those with hypertension (11.3 vs 9.4, P = 0.003) but only a marginally significant difference was discerned for the ESS scores between subjects with AHI ≥15/h and AHI <15/h (P = 0.075). A significant interaction between hypertension and OSA status on daytime sleepiness was observed from the analysis of variance (P = 0.02). The adjusted mean ESS score for the group of normotensive subjects with moderate to severe OSA (13.11) was significantly higher than the other three groups, namely, normotensive subjects with mild OSA (9.35), hypertensive subjects with mild OSA (9.70), and hypertensive subjects with moderate to severe OSA to (9.43). In conclusion, subjective daytime sleepiness of normotensive subjects with moderate to severe OSA was significantly more severe than other subjects.
