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

objectiveThe aim of this nationwide age- and sex- matched longitudinal follow up study is to determine the risk of Parkinson's disease (PD) associated with ischemic stroke in Korea.

methodsPatient data were collected from the National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS). PD was identified using the International Classification of Diseases (ICD) 10-CM code G 20. In total, 6,475 patients were enrolled in the PD group from the NHISS. After subtracting 1,039 patients who underwent hospitalization less than once or those who visited an outpatient clinic less than two times, 5,259 patients who were diagnosed after January 1, 2004 ultimately participated in this study. After case-control match was done through 1:5 age- and sex- stratified matching, 26,295 individuals were chosen as control. Kaplan-Meier method and Cox proportional hazard regression analysis were performed to evaluate the risk of ischemic stroke in PD.

resultsThe hazard ratio of ischemic stroke in the PD group was 3.848 (95% confidence interval (confidence interval [CI]): 3.14-4.70) after adjusting for age and sex. The adjusted hazard ratio of ischemic stroke in PD group was 3.885 (95% CI: 3.17-4.75) after adjusting for comorbidities. According to subgroup analysis, in male and female and non-diabetes and diabetes and non-hypertension and hypertension and dyslipidemia and non-dyslipidemia subgroups, ischemic stroke incidence rates were significantly higher in the PD group than those in the control group.

conclusionsThis nationwide longitudinal study suggests an increased risk of ischemic stroke in PD patients.
