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

The coexistence of sleep-disordered breathing (SDB) and hypertrophic obstructive cardiomyopathy (HOCM) has widely been recognized; however, the impact of percutaneous transluminal septal myocardial ablation (PTSMA) for HOCM on SDB remains unknown. Herein, we examine cardiorespiratory polygraph parameters in patients with drug-refractory HOCM before and after PTSMA. Forty consecutive drug-refractory HOCM patients, admitted to Keio University Hospital, and who underwent cardiorespiratory polygraphy were retrospectively analyzed. Cardiorespiratory polygraphy was performed before and after PTSMA if patients underwent PTSMA. Patients with an apnea-hypopnea index (AHI) ≥5/h were considered to have SDB. The total number of central sleep apneas, obstructive sleep apneas, and hypopnea events was evaluated. Thirty-two out of 40 patients (80%) with drug-refractory HOCM had SDB. All patients experienced relief of heart failure-associated symptoms after PTSMA. The severity of SDB was found to be correlated with left atrial diameter. The AHI decreased after PTSMA [before 15.4 (range 10.9-23.5)/h vs. after 13.1 (8.3-17.8)/h, P = 0.02]. Especially, the hypopnea index decreased after PTSMA. The average and lowest arterial oxygen saturation also increased after PTSMA (94.2 ± 1.9-95.7 ± 1.6%, P = 0.009; 81.3 ± 5.7-85.8 ± 4.8%, P = 0.012, respectively). In patients with drug-refractory HOCM, PTSMA decreased the AHI and improved arterial oxygen saturation measures. Thus, invasive treatment of the left ventricular obstruction ameliorates the severity of SDB, in addition to improving heart failure status.
