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

backgroundBenign paroxysmal positional vertigo (BPPV) is a common cause of vertigo precipitated mainly by changes in head position for example during sleep. The relationship between sleep quality and BPPV has not been studied sufficiently. We decided to compare sleep quality between posterior canal BPPV patients and controls.

methodsA total of 120 patients with posterior canal BPPV and 120 controls without BPPV were included. Demographic data as well as body mass index (BMI), cigarette smoking and medical history of the subjects were documented. The sleep quality of the participants was assessed using the Pittsburgh Sleep Quality Index (PSQI).

resultsMean scores in subjective sleep quality (0.48 vs. 0.19; P = 0.002), sleep disturbances (2.97 vs. 1.85; P = 0.007), use of sleep medications (0.6 vs. 0.25; P = 0.001), and daytime dysfunction (0.76 vs. 0.47; P = 0.07) were significantly higher in the BPPV group than in control group. Poor sleep quality (i.e., total PSQI score >5) was found in 42 patients in the BPPV group (35%) and in 16 controls (13.3%); P < 0.001. Poor sleep quality was significantly more common in those whose vertigo attacks had been started more than 12 months earlier (19 of 33 cases, 57.6%) than the patients whose symptoms had started in the past 12 months (23 of 87 cases, 26.4%); P = 0.001.

conclusionPatients with posterior canal BPPV have poorer sleep quality when compared to controls without this condition, especially in women and those with disease duration longer than 12 months. These finding suggest that close attention should be paid to sleep quality of patients with BPPV.
