The importance of classifying central hypopneas: a call to action.
Review in Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Obstructive and central sleep apnea share pathophysiologic features and often coexist within individual patients. There is general agreement on the criteria for scoring obstructive and central apneas but less guidance and clarity on how and when to classify obstructive and central hypopneas. This paper is an expert panel discussion that examines the importance of accurately classifying obstructive from central hypopneas and the implications of this distinction for both diagnosis and treatment of sleep-disordered breathing. The physiologic and polysomnographic features that allow hypopneas to be classified as either obstructive or central are discussed. When hypopneas are systematically classified, a substantial number of patients are found to have a high proportion of coexisting central disease. The authors discuss how hypopnea classification has growing importance in evaluating patients for neurostimulation and emerging pharmacologic therapies. Finally, the authors outline the need for reproducible approaches to hypopnea classification.
