Comparative Treatment Strategies for Obstructive Sleep Apnea and Their Relationships with Aberrant Driving Behaviors: Taxi Drivers in Taipei Metropolitan Area.
Article in Nature and science of sleep, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Study Objectives: Obstructive sleep apnea (OSA) is prevalent among professional drivers and is associated with an increased risk of aberrant driving behaviors (ADBs). This study evaluated and compared the effectiveness of continuous positive airway pressure (CPAP) and conservative treatments in mitigating ADBs and improving sleep health among urban taxi drivers. Methods: In this prospective non-randomized comparative study, taxi drivers diagnosed with OSA through polysomnography were assigned to either the CPAP group or the conservative treatment group. Home-based sleep parameters (oxygen desaturation index [ODI], cyclic variation of the heart rate index [CVHRI], and chest effort index [CEI]) were measured using wearable devices. Driving data were recorded with a validated navigation application. Subjective measures such as Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and the 27-item Driving Behavior Questionnaire (DBQ) were also collected. Pre- and post treatment outcomes were compared within and between groups using non-parametric statistical tests following the 3-month treatment. Results: Twenty-four taxi drivers were enrolled, with 13 in the CPAP group and 11 in the conservative treatment group. CPAP treatment significantly improved objective and subjective measures of sleep health and driving performance, evidenced by decreases in PSQI (p=0.04), ESS (p=0.01), and DBQ errors (p<0.01) and lapses (p=0.03). Additionally, the occurrence of ADBs per 20 km decreased (p<0.01), and sleep disorder indices improved (ODI, p<0.01; CEI, p=0.03). Conclusion: The conservative treatment group showed no significant changes in these measures. CPAP demonstrated its potential as a primary intervention for occupational drivers with severe OSA. Conservative treatment showed limited effectiveness and could serve as a supplementary approach.
