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.
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
introductionCompliance or adherence with positive airway pressure (PAP) therapy is a major issue in obstructive sleep apnea (OSA). The telemonitoring gives an opportunity to track a group of patients on cloud-based devices. In this study, we followed up patients with this cloud-based method for more than a year and followed up two different cohorts who are on continuous PAP (CPAP) and auto adjusting PAP (APAP) devices. The main objective was to judge whether one device scores over the other.
methodsThis was a retrospective study. We included 60 patients in the CPAP group and 80 patients in the APAP group in the study who are using the device for 1 year or more; they all were on cloud-based devices, and for them, we had data of completed 1 year at least. The data were reviewed periodically for compliance, AHI (Apnea-Hypopnea Index), and leak and compared.
resultsBoth the groups were matched in terms of age, BMI, and AHI. Adherence at 365 days was significantly more (P < 0.001) for CPAP than APAP. Overall adherence was not lesser than 60% for CPAP in any patient. The mean AHI was 1.48 in CPAP group and 2.30 in APAP group. When we measured the leak in CPAP versus APAP group, it was 0.53 liter/minute more in CPAP group than in APAP group, but it was statistically non-significant (P = 0.8553). The mean pressure level between APAP and CPAP was 11.11 cmH2O in CPAP group and 11.62 cm H2O in APAP group, and it was again statistically non-significant (P = 0.1960). CPAP group used the machine 5.77 hours average, while APAP group used it for 4.51 hours average.
conclusionCPAP adherence at 1 year was better over APAP in this study, which has a large cost implication.
