Impact of Wechat-based prehospital data transmission on reperfusion times in ST-elevation myocardial infarction: a prospective observational study.
Article in Clinics (Sao Paulo, Brazil), 2026. 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
objectivesEarly diagnosis of acute ST-segment Elevation Myocardial Infarction (STEMI) is important for the treatment of patients. A Class I evidence demonstrates that every 30-minute delay in PCI is linked to a 7.5% relative increase in 1-year mortality
methods409 eligible STEMI patients (May 2022-November 2024) were grouped by WeChat-based transmission use: 96 in the observation group and 313 in the control group. Baseline data, medical history, and key times (S-to-FMC, d-to-B, TIT) were compared. Factors influencing WeChat-based transmission use were analyzed via SPSS 22.0 (p < 0.05 significant).
results96 (23.4%) patients in the WeChat-based transmission group and 313 (76.6%) patients in the N-WeChat group were enrolled. S‑to‑FMC time was associated with lower median values in the WeChat‑based transmission group (median 75 vs. 120 minutes, p < 0.05); similar patterns were seen for D‑to‑B time (50 vs. 67 minutes, p < 0.05) and total ischemia time (121.5 vs. 150.0 minutes, p < 0.05). Shorter time to Acute Myocardial Infarction (AMI) diagnosis, as well as shorter D‑to‑B and TIT times, were observed among patients in the WeChat‑based transmission group relative to patients in the non‑WeChat‑based transmission group.
conclusionWeChat-based transmission was associated with shorter S-to-FMC, d-to-B, and TIT times during patient transfer for PCI. However, it is not fully used for transporting chest pain patients in and around Shijiazhuang City. Therefore, strengthening WeChat-based transmission function in public education of pre-hospital rescue remains the focus of our future work.
