Article in Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01538069 (Comparison Between Exercise Training and CPAP Treatment for Patients With Heart Failure and Sleep Apnea.), which is not on this map. Cited by 2 papers.

1 · What the graph read from 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.

Abstract

STUDY

objectivesPatients with congestive heart failure (CHF) frequently exhibit an elevated ratio of minute ventilation over CO

methodsThis preliminary study involved 70 patients with stable CHF and a spectrum of OSA severity who underwent full-night polysomnography, echocardiography, and cardiopulmonary exercise testing. Peak oxygen consumption and the VE/VCO

resultsThere was significant positive correlation between the apnea-hypopnea index and the VE/VCO

conclusionsIn patients with CHF, the VE/VCO CLINICAL
