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

contextOnly a few studies have reported a correlation between severe obstructive sleep apnea syndrome (OSAS) and hypogonadism in patients with obesity, regardless of body mass index (BMI). However, longitudinal studies exploring the role of continuous positive airway pressure (CPAP) on gonadal function are scanty.

objectiveThis work aimed to investigate in men with severe/complicated obesity the role of OSAS in decreasing testosterone levels and evaluate the effects of CPAP on hormonal status.

methodsThis cross-sectional study consecutively enrolled 204 male inpatients with complicated severe obesity, without known hypogonadism. Polysomnography (or overnight oximetry during CPAP) and blood tests for inflammation and metabolic and hormonal profiles were performed. "Decompensated OSAS" was defined as an Apnea/Hypopnea Index (AHI) in newly diagnosed, or Oxygen Desaturation Index (ODI) in treated patients, above 30 events/hour. A multiple linear regression was implemented to identify the independent factors correlated with total testosterone (TT). Lastly, a longitudinal study of 14 newly diagnosed patients was performed to evaluate the effects of CPAP on TT after 3 months of treatment.

resultsA total of 127 of 204 patients showed low TT (≤10.4 nmol/L). BMI, type 2 diabetes, C-reactive protein, and decompensated OSAS were independently associated with TT (P = .039; P = .006, P = .003, and P = .014, respectively). After 3 months of CPAP therapy, TT was higher (P = .009) and ODI was associated with such improvement, independently of BMI (P = .04).

conclusionDecompensated OSAS was found to correlate with low testosterone in men with severe obesity. Moreover, CPAP therapy was shown to improve TT independently of BMI changes.
