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

Objective: Insomnia is a highly prevalent disorder among patients suffering from stroke. The association between insomnia and stroke mortality is less studied, particularly using the latest diagnostic criteria. The current study examined the relationship between insomnia and mortality among patients with first-evonal hazard models were used to calculate HRs for stroke er stroke in China. Methods: Patients with acute cerebrovascular diseases (stroke) were recruited from 56 hospitals in mainland China. Insomnia was defined as difficulty falling asleep, or difficulty staying asleep or waking up early, for at least two consecutive visits. Demographic data, medical history and clinical data were collected. Four follow-up visits occurred within the first year after stroke, and the last follow-up call was conducted 6 years later. Cox proportional hazard models were used to calculate HRs for stroke mortality. Results: Insomnia was reported by 38.4% (489/1273) of patients at baseline. During the 6 years of follow-up, after adjusting for all confounders, insomnia was found to be associated with increased mortality (HR=1.66, 95% CI 1.10 to 2.48). Old age (HR=1.08, 95% CI 1.06 to 1.10), stroke recurrence in the first year of follow-up (HR=2.53, 95% CI 1.48 to 4.31) and stroke survivors with hypertension (HR=1.62, 95% CI 1.04 to 2.53) had substantially higher risk of mortality. Conclusions: Besides old age, stroke recurrence in the first year of follow-up and hypertension, insomnia is associated with increased risk of mortality in patients with first-ever stroke in China. More studies about prompt and efficient interventions for insomnia are expected in the future. Trial registration number: rctn62169508.
