Treatments, medical expenses and complications of hospital outpatient healthcare associated with stroke in patients with diabetes in China: a retrospective analysis of the Beijing Municipal Medical Insurance Database.
Observational study in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectivesDiabetes is closely associated with risk of stroke and its adverse sequelae. Approximately 20%-33% of patients with stroke have diabetes. In China, however, it is unclear how stroke affects healthcare utilisation, medications and complications among people with diabetes. This study aimed to analyse the clinical characteristics, treatment options, medical expenses and complications of hospital outpatient healthcare associated with stroke in patients with diabetes in China.
designA retrospective, multicentre, observational study.
settingBeijing Municipal Medical Insurance Database, with data from 2016 to 2018.
participantsThe study included patients with diabetes whose data included 2016-2018 outpatient medication records and who had Beijing medical insurance. Patients who did not have continuous prescription records for more than 2 months were excluded from the analysis. In total, 2 853 036 people with diabetes were included, and patients who had and did not have a stroke were compared.
resultsIn our study, 19.75%-22.30% of patients with diabetes suffered from stroke between 2016 and 2018. The average annual medical cost for a patient diagnosed with diabetes is ¥9606.65, and the cost increases to ¥13 428.39 when diabetes was combined with stroke; thus, stroke increases the medical cost for patients with diabetes by 39.78% (p<0.0001). Among patients with diabetes who had a stroke, 4.76 medications were used (1.8 hypoglycaemic drugs and 2.97 non-hypoglycaemic drugs); these numbers were significantly greater than for patients with diabetes who did not have a stroke receiving both hypoglycaemic drugs and non-hypoglycaemic drugs (p<0.0001). Among patients with diabetes who did not have a stroke, 3.58 medications were used (1.66 hypoglycaemic drugs and 1.92 non-hypoglycaemic drugs). Patients with diabetes who had a stroke also had significantly greater incidences of diabetic peripheral neuropathy, diabetic kidney disease, diabetic retinopathy and diabetic angiopathy than those who did not have a stroke (p<0.0001). These drugs and costs increased with the number of complications (p<0.0001). The increased medical costs for each specific complication are also listed. We also analysed the medical costs and medication regimens stratified by sex, age group and complications.
conclusionsStroke is associated with a significant increase in complications and medications for patients with diabetes and greatly adds to the economic burden of these patients. Early identification of stroke risk factors in patients with diabetes, as well as targeted poststroke diabetes management, is crucial from a socioeconomic perspective for a comprehensive management and treatment of stroke in patients with diabetes.
