Barriers to Timely Percutaneous Coronary Intervention (PCI) in Rural vs. Urban Settings: A Health System Approach.
Article in Cureus, 2025. 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
introductionTimely primary percutaneous coronary intervention (PCI) is crucial for reducing morbidity and mortality in ST-elevation myocardial infarction (STEMI). Delays in rural populations are often driven by geographic, patient-related, and system-level barriers.
objectiveThe objective of the study is to evaluate and compare barriers to timely PCI in rural versus urban STEMI patients, identify independent predictors of treatment delay, and quantify their impact on reperfusion times.
methodsThis cross-sectional study enrolled 273 adult STEMI patients undergoing primary PCI at District Headquarter (DHQ) Teaching Hospital, Mardan, over 12 months (137 rural and 136 urban). Patients who received prior fibrinolysis, were referred from other PCI-capable centers, or declined participation were excluded. Patient- and system-level barriers were operationally defined and measured using a structured, pre-tested questionnaire supplemented by medical record review. Patient-level barriers included delayed symptom recognition, transport difficulties, and financial constraints; system-level barriers included off-hour PCI unavailability, inter-facility transfer delays, and referral inefficiencies. Door-to-balloon and symptom-to-door times were recorded and analyzed, adjusting for age, gender, comorbidities, and transport mode. Missing data were handled via listwise deletion. Multivariate logistic regression was conducted after testing model assumptions and assessing multicollinearity to identify independent predictors of PCI delay.
resultsRural patients had significantly longer door-to-balloon (105.5 ± 15.8 vs. 84.1 ± 11.9 min, p < 0.001) and symptom-to-door (295 ± 80 vs. 145 ± 50 min, p < 0.001) times compared to urban patients. Delays > 90 minutes occurred in 82.5% of rural versus 27.9% of urban patients. Multivariate logistic regression identified rural residence (adjusted odds ratio (AOR) 4.75, 95% confidence interval (CI) 2.95-7.65), patient-related barriers (AOR 2.35, 95% CI 1.50-3.68), and system-related barriers (AOR 2.80, 95% CI 1.85-4.25) as independent predictors of PCI delay.
conclusionRural STEMI patients experience significant delays in receiving primary PCI, primarily due to patient- and system-level barriers. Interventions targeting health education, pre-hospital transport, and referral streamlining are essential to reduce rural-urban disparities and improve clinical outcomes, in line with international guideline recommendations for timely reperfusion.
