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
objectivesSleep apnea is a chronic disorder associated with multiple recognized comorbidities. Only a few studies focus on evaluating the cognitive profile in patients diagnosed with sleep apnea. The aim of the study was to assess the cognitive functions in this population using the Montreal Cognitive Assessment.
methodsThe study cohort was 1,445 adult patients who were referred for overnight polysomnography, 764 cases and 681 healthy controls. All participants' clinical data and comorbidities were taken, and they all performed overnight polysomnography and Montreal Cognitive Assessment.
resultsA significantly higher proportion (57.5%) of sleep apnea groups were males; 15.7% were illiterate compared to the non-sleep apnea group. Hypertension and diabetes mellitus were significantly more prevalent among studied patients with sleep apnea, and the mean total score for the Montreal Cognitive Assessment scale was significantly lower among those with sleep apnea at
conclusionsLogistic regression analysis was conducted to investigate predictors for occurrence of cognitive impairment (Montreal Cognitive Assessment score < 26) among the studied sample (n = 1,445). The overall model was significant at CITATION: Mekky JF, Yousof S, Elsayed I, Elsemelawy R, Mahmoud H, Elweshahi H.
