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

backgroundStroke is among the leading causes of death in Germany and one of the main reasons for handicap and disability. The risk factors for stroke include hypertension, metabolic disorders, and diabetes. An estimated 250 000 persons sustain a stroke in Germany each year. German data on the occurrence of stroke, and of recurrent stroke in particular, are still inadequate. The main objective of this study was to determine the frequency and timing of recurrent stroke.

methodsThe analyses were based on routine data of the AOK statutory health insurance fund in the German federal state of Lower Saxony. Inpatient billing and diagnosis data were used to identify initial and recurrent strokes (ICD-10 I60-I64). The derived incidence and prevalence were standardized for age and sex. The risks of recurrence and mortality were estimated with Kaplan-Meier analyses and Cox regressions.

resultsIn 2010/2011, the standardized incidence of stroke was 292 per 100 000 persons per year, and the standardized prevalence was 336 per 100 000 persons. The risk of recurrence was 1.2% in the first 30 days, 3.4% within 90 days, 7.4% within 1 year, and 19.4% within 5 years. The mortality after an initial stroke was 6.8% in the first 30 days, 9.4% within 90 days, 17.0% within 1 year, and 45% within 5 years. Patients with hemorrhagic strokes had higher mortality. Treatment in a stroke unit was associated with lower mortality.

conclusionPatients with acute stroke should be treated in a specialized center whenever possible. After hospital discharge, stroke patients should be followed up at short intervals and any risk factors for stroke should be treated.
