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

purposeThere is limited information on the association between pre-treatment insomnia symptoms and dysfunctional sleep beliefs with continuous positive airway pressure (CPAP) adherence in veterans with obstructive sleep apnea (OSA). Our aims were to describe demographic and sleep characteristics of veterans with and without comorbid insomnia and determine whether pre-treatment insomnia symptoms and dysfunctional sleep beliefs predict CPAP use after 6 months of therapy.

methodsHispanic veterans attending the Miami VA sleep clinic were recruited and completed the insomnia severity index, the dysfunctional sleep belief and attitude scale (DBAS), and other questionnaires. Participants were asked to return after 7 days and 1 and 6 months to repeat questionnaires and for objective CPAP adherence download. Hierarchical regression models were performed to determine adjusted associations of pre-treatment insomnia symptoms and DBAS sub-scores on 6-month mean daily CPAP use.

resultsFifty-three participants completed the 6-month follow-up visit with a mean CPAP use of 3.4 ± 1.9 h. Veterans with comorbid insomnia had lower mean daily CPAP use (168 ± 125 vs 237 ± 108 min, p = 0.04) and lower percent daily CPAP use ≥ 4 h (32 ± 32 vs 51 ± 32%, p = 0.05) compared to participants without insomnia. In adjusted analyses, pre-treatment insomnia symptoms (early, late, and aggregated nocturnal symptoms) and sleep dissatisfaction were predictive of lower CPAP use at 6 months. Pre-treatment dysfunctional sleep beliefs were not associated with CPAP adherence.

conclusionsPre-treatment nocturnal insomnia symptoms and sleep dissatisfaction predicted poorer 6- month CPAP use. Insomnia treatment preceding or concurrent with CPAP initiation may eliminate a barrier to regular use.
