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

backgroundObstructive sleep apnoea (OSA) is a disorder characterized by apnoeas and hypopnoeas due to repetitive upper airway collapse during sleep. So far, there are no published data regarding quality of life (QoL) and adherence to CPAP among patients with OSA in India. This study aims to measure sleepiness and QoL of patients before and after effective CPAP use in patients with OSA.

methodNewly diagnosed subjects with OSA were included, and socio-demographic risk factors and anthropomorphic measures were collected. Epworth sleepiness scale (ESS) and short sleep apnoea quality of life index (SAQLI) were administered before and after a minimum of 4 weeks of domiciliary CPAP use. While short SAQLI is a disease-specific questionnaire, ESS measures excessive daytime sleepiness.

resultsIn 92 subjects age range was 28-74 years, mean age 49.7 ± 11.3 years, and male:female ratio was 70:22. Mean BMI was 32.1 ± 6.4 kg/sq.m; mean neck circumference was 39.4 ± 3.4 cm; 56 subjects had Mallampati score of 3 or 4. One-month follow-up was completed by 34 subjects who reported a mean of 5.8 ± 1.1 hours/night usage of CPAP. Mean ESS score was 11.31 ± 5.6 at baseline vs 6.9 ± 3.3 after 1 month (p = 0.02), and baseline short SAQLI score was at 2.54 ± 1.26 vs 1.38 ± 0.87 after 1 month (p = 0.0001).

conclusionsSubjects reported adequate compliance with CPAP at 1 month, and both ESS and short SAQLI showed a significant improvement in these patients. CPAP compliance improved both QoL and sleepiness in patients with OSA.
