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.

2 · The registry

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

objectivesThe Belun ring is a new home sleep apnea testing device using a pulse oximeter sensor and a neural network algorithm, but its data in children are limited. This study aims to evaluate the correlation and agreement of the Belun ring, compared with polysomnography (PSG) and determine the diagnostic accuracy of the Belun ring for moderate-to-severe obstructive sleep apnea (OSA).

methodsThis is a cross-sectional observational study in children aged 5-18 years with suspected OSA between June 2023 and February 2024. The Belun ring and PSG were undertaken on eligible participants to assess apnea-hypopnea index (AHI) in the same sleep test session.

resultsOf 75 children enrolled, OSA was diagnosed in 74 children by PSG. The Belun AHI (B-AHI) was moderately correlated with the PSG AHI (P-AHI) (

conclusionsDespite the correlation, the difference in AHI between the Belun ring and PSG in children was noted. Either single or multiple B-AHI cut-offs to diagnose, include or exclude moderate-to-severe OSA may be valuable, but their implementation must be approached with caution. CLINICAL
