Transradial versus transfemoral approach for percutaneous coronary intervention in patients with ST-elevation myocardial infarction complicated by cardiogenic shock: a systematic review and meta-analysis.
Synthesis in European heart journal. Quality of care & clinical outcomes, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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 ST-elevation myocardial infarction (STEMI), transradial access (TRA) for percutaneous coronary intervention (PCI) is associated with less bleeding and mortality than transfemoral access (TFA). However, patients in cardiogenic shock (CS) are more often treated via TFA. The aim of this meta-analysis is to compare the safety and efficacy of TRA vs. TFA in CS.
methodsSystematic review was performed querying PubMed, Google Scholar, Cochrane, and clinicaltrials.gov for studies comparing TRA to TFA in PCI for CS. Outcomes included in-hospital, 30-day and ≥1-year mortality, major and access site bleeding, TIMI3 (thrombolytics in myocardial infarction) flow, procedural success, fluoroscopy time, and contrast volume. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using random effects models.
resultsSix prospective and eight retrospective studies (TRA, n = 8032; TFA, n = 23 031) were identified. TRA was associated with lower in-hospital (RR 0.59, 95% CI 0.52-0.66, P < 0.0001), 30-day and ≥1-year mortality, as well as less in-hospital major (RR 0.41, 0.31-0.56, P < 0.001) and access site bleeding (RR 0.42, 0.23-0.77, P = 0.005). There were no statistically significant differences in post-PCI coronary flow grade, procedural success, fluoroscopy time, and contrast volume between TRA vs. TFA.
conclusionsIn PCI for STEMI with CS, TRA is associated with significantly lower mortality and bleeding complications than TFA while achieving similar TIMI3 flow and procedural success rates.
