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

STUDY

objectivesThe Insomnia Severity Index (ISI) has been used to define insomnia symptoms in individuals with obstructive sleep apnea (OSA). However, whether distinct ISI profiles exist in individuals with OSA is unclear. The aims of this study were to determine (1) empirically-based ISI profiles in veterans with OSA and (2) predictors of these ISI profiles.

methodsParticipants were 630 veterans with a new diagnosis of OSA over a 12-month period. Individuals completed the ISI and other questionnaires on the polysomnography (PSG) night. Latent profile analysis was performed to detect ISI subgroups based on individual ISI items. Age, Charlson Comorbidity Index, apnea-hypopnea index (AHI), mood disorder, posttraumatic stress disorder, and chronic pain diagnoses were used to predict between ISI profiles.

resultsLatent profile analysis identified five ISI subgroups in veterans with OSA. The "asymptomatic" group (12% prevalence) had low scores across all ISI items. The "moderate insomnia" (30% prevalence) and "severe insomnia" (44% prevalence) groups had elevated scores for all ISI items but differing in severity. Last, the "moderate" (6% prevalence) and "severe daytime symptoms" groups (8% prevalence) were characterized by absence of nocturnal complaints but high scores on daytime impairment items. Age, AHI, mood disorder, posttraumatic stress disorder and chronic pain diagnoses discriminated between ISI profiles.

conclusionsWe describe data-driven ISI profiles in veterans with OSA. Older age was associated with lower insomnia and daytime symptom complaints whereas psychological comorbidities were related to more severe insomnia. Caution should be used in interpreting the ISI score in individuals with OSA because a subset had elevated total scores without insomnia.
