Sleepiness and nocturnal hypoxemia in Peruvian men with obstructive sleep apnea.
Article in Sleep & breathing = Schlaf & Atmung, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeTo evaluate the intensity of nocturnal hypoxemia associated with sleepiness in Peruvian men with a diagnosis of obstructive sleep apnea (OSA).
methodsWe carried out a secondary data analysis based on a study which includes patients with OSA who were seen in a private hospital in Lima, Peru from 2006 to 2012. We included male adults who had polysomnographic recordings and who answered the Epworth sleepiness scale (ESE). The intensity of nocturnal hypoxemia (oxygen saturation ≤90%) was classified in four new categories: 0, <1, 1 to 10 and >10% total sleep time with nocturnal hypoxemia (NH). When the ESE score was higher than 10, we used the definitions presence or absence of sleepiness. We used Poisson regression models with robust variance to estimate crude and adjusted prevalence ratios (PR) for association between sleepiness and NH.
results518 male patients with OSA were evaluated. Four hundred and fifty-two (87%) patients had NH and 262 (51%) had sleepiness. Of the 142 (27.4%) patients who had >10% total sleep time with NH, 98 (69.0%) showed sleepiness and had a greater probability of sleepiness prevalence, with a crude PR of 1.82 (95% CI 1.31-2.53). This association persisted in the multivariate models.
conclusionsWe found an association between NH and sleepiness. Only patients with the major intensity of NH (over 10% of the total sleep time) had a greater probability of sleepiness. This suggests that sleepiness probably occurs after a chronic process and after overwhelming compensatory mechanisms.
