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

backgroundHigh rates of non-adherence to continuous positive airway pressure (CPAP) in obstructive sleep apnoea hamper good clinical outcomes. Current recommendations assumes two behaviours (adherence and non-adherence) and days 7-90 follow-up post-CPAP initiation mitigates against non-adherence.

objectivesTo investigate associations between early CPAP-usage behaviours and (1) CPAP adherence at month 3 of treatment and (2) sleep centres' treatment pathways (the procedures patients undergo that may affect barriers or facilitators of CPAP adherence).

methodsWe conducted growth mixture modelling (GMM) on retrospective data from 1000 patients at 5 UK sleep centres. Night 1 to month 3 telemonitored CPAP-usage data were downloaded from 200 patients per centre who started CPAP in 2019 (100) or 2020 (100). Adherence was defined using accepted criteria (mean CPAP-usage ≥4 hours/night for ≥70% of nights).

resultsGMM identified six distinct CPAP-usage behaviour patterns over month 1. In four (54% of patients), CPAP-usage increased or decreased, in two (remaining 46%), CPAP-usage/non-usage was consistent. 62% of the cohort were non-adherent by month 3, despite pathways following current recommendations. 98% of patients who were non-adherent by month 3 were already non-adherent by month 1. Regression analysis with a separate dataset demonstrated that early CPAP-usage behaviour explained 86% of the variance in CPAP non-adherence at month 3.

conclusionsThese data, supported by previous work, indicate that recommended day 30-90 follow-up is too late to prevent CPAP non-adherence. Determining CPAP-usage behavioural pattern in week 2 identifies risk of CPAP non-adherence at month 3 and permits the possibility of tailored interventions.
