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

objectivesTo describe sleep-disordered breathing (SDB) in young boys with Duchenne muscular dystrophy (DMD) and its relationship with pulmonary function tests (PFTs). STUDY

designThis retrospective study examined diagnostic polysomnogram and PFT data of boys younger than 18 years with DMD and treated with steroids. Spirometry, respiratory muscle strength, body mass index (BMI), sleep architecture variables, and indices of SDB were analyzed. We examined the effect of PFT measures on the risk of each type of respiratory event using logistic regression and have reported results as OR (95% CI).

resultsSubjects included 110 boys with DMD, mean age 11.5 (5.6-17.9) years. Mean (±SD) percent forced vital capacity predicted was 79.5% ± 29.1%. Mean BMI for all subjects was 21.9 ± 7.0 kg/m(2), and mean BMI z-score was 0.65 ± 1.93. Seventy (63.6%) subjects had obstructive sleep apnea; 37 (33.6%) subjects had central sleep apnea; 18 (17%) subjects had hypoventilation. Median (IQR) Apnea Hypopnea Index was 2.9 (1.6-6.9) and median Obstructive Index was 1.5 (0.5-3.8). Obstructive Index during rapid eye movement sleep positively correlated with BMI (r = 0.33, P = .002), BMI z-score (r = 0.22, P = .04), and age (r = 0.31, P = .004). Lower forced vital capacity was associated with increased risk of hypoventilation (OR 0.8, P = .001).

conclusionSDB is common in young boys with DMD treated with steroids. It is manifest with rapid eye movement-obstructive sleep apnea, often severe, and strongly influenced by BMI.
