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

backgroundIn rural settings, women with ST-elevation myocardial infarction (STEMI) are less likely to receive timely reperfusion than men. We explore factors that may impact time to reperfusion by sex for patients with STEMI.

methodsWe conducted a cohort study of adults with STEMI activations from 2016 to 2020 using regional North Carolina STEMI registry data, which included eight rural emergency medical services (EMS) agencies and three percutaneous coronary intervention (PCI) centres. The primary outcome was EMS first medical contact to PCI in ≤90 min. By sex, we evaluated prehospital time intervals (dispatch, response, time-to-ECG, catheterisation laboratory activation, on-scene, transport and total EMS) and door-to-balloon time with clustered Wilcoxon rank-sum tests. We also evaluated agency and patient factors associated with timely reperfusion using generalised estimating equations.

resultsOf the 365 patients included, 30.1% (110/365) were female with a mean age of 62.5±12.7. Fewer women received PCI within 90 min compared with men (43.6% vs 67.8%, p<0.001). Women also experienced significantly longer total EMS time (42.5 vs 40.0 min, p=0.049) and door-to-balloon time (48.5 vs 40.0 min, p=0.01). Other time intervals were similar. After adjustment, women without exertional symptoms, with diabetes or with hypercholesterolaemia had lower odds of timely reperfusion. Among men, lower odds of timely reperfusion were observed among those without pain, who had catheterisation lab activation between 17:00 and 07:00, who were older or who had farther transport.

conclusionIn rural settings, women without exertional chest pain and those with comorbid conditions were less likely to have timely reperfusion. Women experienced significantly longer total EMS time and door-to-balloon time than men.
