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

objectiveTo evaluate the impact of ambient temperature and altitude exposure on the burden of stroke in a Chinese cohort.

methodsThis study was conducted using data from the National Stroke High-Risk Population Screening System 2020, which assess the overall prevalence, incidence, and mortality rate of stroke in China. For this study, we obtained the annual mean ambient temperature, diurnal temperature range, and altitude for each city. Body mass index (BMI) of participants were calculated.

resultThe sample comprised 676,394 adults aged 40 years or older from 170 cities in 31 provinces in China. A negative linear relationship between mean ambient temperature and stroke risk (incidence and prevalence) as well as a negative association between mean ambient temperature and stroke mortality had been found. A nonlinear relationship with decreased risk in both high and low diurnal temperature range is observed for stroke burden (incidence, prevalence, and mortality). There is no significant correlation between city altitude and stroke burden. The U-shaped relationships of BMI with the incidence and prevalence of stroke indicate that the lowest incidence and prevalence are observed when BMI is approximately 20.

conclusionOverall, our study provides important insights into the environmental and individual factors that contribute to the burden of stroke in China, and may inform public health interventions aimed at reducing this burden.
