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

objectiveTo study sleep quality and cognitive status and their correlation in patients with persistent postural and perceptual dizziness (PPPD).

methodsWe assessed sleep quality and cognitive function among 70 patients with PPPD and 70 age-matched heathy volunteers using Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Pittsburgh Sleep Quality Index and polysomnography (PSG).

resultsThe patients had a mean MMSE score of 25.10±3.87 and a mean MoCA score of 23.10±6.11, both suggesting mild cognitive impairment of the patients. The mean PSQI score of the patients was 14.60 ± 2.06, suggesting moderate insomnia among the patients. The MMSE scores in 3 dimensions (attention, memory and recall ability) and the dimension scores of MoCA for visual space and executive ability, attention and delayed recall all showed significant positive correlations with PSQI scores for sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disorders and daytime dysfunction.

conclusionsModerate sleep disorder and mild cognitive dysfunction are common in PPPD patients. Sleep quality is correlated with cognitive function among these patients, suggesting that improving sleep quality of the patients helps to improve their cognitive function.
