Impact of continuous positive airway pressure and oxygen on health status in patients with coronary heart disease, cardiovascular risk factors, and obstructive sleep apnea: A Heart Biomarker Evaluation in Apnea Treatment (HEARTBEAT) analysis.
Trial report in American heart journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 4 of them syntheses that pooled 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.
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
introductionObstructive sleep apnea (OSA) is associated with impaired health-related quality of life (HRQL). Treatment with continuous positive airway pressure (CPAP) has variable impacts on HRQL, and this may be influenced by patient's tolerance of therapy. The objective is to determine the impact of nocturnal supplemental oxygen (NSO) and CPAP on HRQL compared with healthy lifestyle education (HLSE) in individuals with OSA.
methodsPatients with coronary heart disease (CHD) or at least 3 major CHD risk factors with apnea-hypopnea index of 15 to 50 events/h were randomized to CPAP, NSO, or HLSE. Health-related quality of life was assessed using the Short-Form 36, and depression was assessed with Patient Health Questionnaire-9 at baseline and 12 weeks. The treatment effect on HRQL change scores through 12 weeks was assessed using multivariable models adjusting for study site, presence of CHD at baseline, race, and baseline HRQL.
resultsA total of 318 patients were randomized to 1 of 3 treatment arms with 1:1:1 ratio and 94% completed baseline and follow-up HRQL instruments. Mean Short-Form 36 scores were similar at baseline in all 3 groups ranging from 41.8±12 to 51.6±12 in various domains. In multivariable models, the CPAP group noted a significantly greater improvement than NSO in mental health (+2.33, 95% CI 0.34-4.31, P=.02) and mental composite score (+2.40, 95% CI 0.40-4.41, P=.02). Conversely, the CPAP group noted less improvement than NSO in physical function (-2.68, 95% CI -4.66 to -0.70, P=.008) and physical composite score (-2.17, 95% CI -3.82 to -0.51, P=.01). Compared with HLSE, vitality and Patient Health Questionnaire-9 improved with CPAP but not with NSO. Significant interactions were noted between treatment effects with larger differences in black and sleepy patients.
conclusionThese data support the use of CPAP for improving vitality, sleepiness, mental health, social functioning, and depressive symptoms in patients with OSA and established CHD or risk factors. Nocturnal supplemental oxygen may have beneficial effects on perceived physical functioning.
