Article in Medical science monitor : international medical journal of experimental and clinical research, 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
BACKGROUND Exploring the factors that impact the time from symptom onset to first medical contact (S2FMC) is crucial for improving outcomes in elderly patients diagnosed with acute ST-segment elevation myocardial infarction (STEMI). This study conducted a retrospective analysis on 282 patients who underwent emergency percutaneous coronary intervention (PCI) or percutaneous transluminal coronary angioplasty (PTCA) in Guangzhou City District to identify significant factors affecting S2FMC. MATERIAL AND METHODS A retrospective analysis was conducted on 282 patients with STEMI who underwent emergency percutaneous coronary intervention (PCI). Descriptive statistics, univariate and multivariate Cox regression analyses were used to identify significant factors affecting S2FMC. Additionally, interactions between risk factors were examined using multivariate logistic regression and the structural equation model (SEM). RESULTS Age (HR=0.984, 95% CI: 0.975-0.993), nature of chest pain (HR=2.561, 95% CI: 1.900-3.458), admission mode (HR=1.805, 95% CI: 1.358-2.400), and vascular characteristics (HR=1.246, 95% CI: 1.069-1.451) were independent influencing factors for S2FMC. Persistent chest tightness/pain, EMS admission, and vascular characteristics (RCADL or LCADL) played a protective role in S2FMC. Among the influencing factors, vascular characteristics (OR=1.072, 95% CI: 1.008-1.141) had an independent effect on the nature of chest pain. Meanwhile, the nature of chest pain (OR=1.148, 95% CI: 1.015-1.298) was an independent influencing factor in the admission mode. CONCLUSIONS Patients with persistent chest tightness/pain, EMS admission, and vascular characteristics (RCADL or LCADL) experienced shorter S2FMC and higher compliance rate (S2FMC ≤180 min). At the same time, age and other vascular features played an inverse role. This study proposes enhancing follow-up and monitoring measures, and shows the consequences of intermittent chest pain should not be disregarded.
