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

backgroundThe national epidemiologic data in mainland China is still absent for moyamoya disease (MMD).

methodsThis study was a nationwide hospital-based observational retrospective study to estimate epidemiological characteristics of MMD. The data was based on the Hospital Quality Monitoring System (HQMS), a national database which covers all tertiary hospitals in mainland China. This system consistently collects medical records including demographic characteristics, diagnoses, procedures, and expenses etc. for all inpatients. MMD was identified by ICD-10 code (I67·5) in HQMS.

findingsA total of 47,443 new-onset patients with total 69,680 hospitalization records from 1312 hospitals during 2016 to 2018 were included. The annual incidence rate was 1·14 per 100,000 inhabitants (95% CI, 1·12-1·16) and approximately a 2-fold increase from 2016 to 2018. The incidence in children (0·18 per 100,000 inhabitants per year; 95% CI, 0·17-0·20) was significantly lower than that in adults (1·40 per 100,000; 95% CI, 1·38-1·42) (

interpretationOur study reported the annual incidence of MMD was 1·14 per 100,000 inhabitants in mainland China during 2016 to 2018, and it was increasing year by year. The geographical distribution of MMD incidence presented as a clustered regional pattern, which may provide new view for future study on the etiology for MMD.
