Sex disparities in pre-hospital delay in patients with acute myocardial infarction: a systematic review and meta-analysis.

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
backgroundPre-hospital delay is a critical determinant of outcomes in acute myocardial infarction (AMI). While sex-based differences in time to presentation have been documented, evidence regarding the association between sex and pre-hospital delay remains inconsistent. This study aimed to determine whether female sex is associated with prolonged pre-hospital delay among patients with AMI.
methodsWe conducted a systematic review and meta-analysis of studies published between 2000 and 2025, retrieved from PubMed and Web of Science. Included studies reported multivariable-adjusted odds ratios (ORs) for the association between sex (female vs. male) and pre-hospital or patient delay in AMI. Risk of bias was assessed using the Agency for Healthcare Research and Quality checklist. Summary ORs were calculated using inverse variance-weighted random-effects models. Heterogeneity was evaluated using I²and Cochran's Q statistics. Publication bias was assessed via funnel plots and Egger's test.
resultsTwenty-nine studies involving 127,409 AMI patients were analysed (21 evaluated pre-hospital delay, 8 focused on patient delay). Female sex was significantly associated with prolonged pre-hospital delay (OR = 1.17, 95% CI = 1.11 to 1.23, I
conclusionSignificant sex disparities exist in pre-hospital delay among AMI patients, with women experiencing longer delays than men. Addressing these gender disparities is crucial for improving timely recognition and management of AMI, ultimately leading to better clinical outcomes and reduced gender-based healthcare inequalities.
