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
Objectives: This study aimed to evaluate the screening rate and the prevalence of obstructive sleep apnea syndrome (OSAS) in patients with apparent resistant hypertension (ARH) attending Sultan Qaboos University Hospital, and to assess sex differences. Methods: A cross-sectional retrospective study was conducted using the data from 500 patients with ARH between January 2018 and January 2023. The cohort included 270 women and 230 men. Data extracted from hospital records included demographic and clinical characteristics, antihypertensive medications, results of OSA screening tools (e.g., Epworth Sleepiness Scale and STOP-Bang questionnaire), and polysomnography outcomes. Results: Of the 500 patients with ARH, 54 (10.8%) were diagnosed with OSAS. Only 6.6% (n = 33) were screened for OSA using the Epworth Sleepiness Scale or STOP-Bang questionnaire, while the majority (93.4%, n = 467) were not screened. Women constituted 54.0% of the cohort and had a higher mean body mass index than men (32.7 kg/m Conclusions: There was a low rate of screening for OSAS among patients with ARH at Sultan Qaboos University Hospital, which may explain the lower-than-expected prevalence observed. Contrary to published literature, OSAS was more frequently diagnosed in women, who were screened more often, suggesting that OSA may be underdiagnosed in men.
