Sex-based disparities in bystander CPR for out-of-hospital cardiac arrest related to non-prescription drug use.
Article in Resuscitation plus, 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
Background: Non-prescription drug toxicity accounts for up to 10% of out-of-hospital cardiac arrests (OHCAs). Bystander cardiopulmonary resuscitation (CPR) improves OHCA outcomes but may be influenced by the patient's sex and the bystander's perceptions of non-prescription drug use. We examined differences in bystander CPR for OHCA of female and male cases with evidence of recent non-prescription drug use. Methods: We used the BC Cardiac Arrest Registry to identify emergency medical system-treated non-traumatic adult OHCAs (2019-2024) with evidence of recent non-prescription drug use. We assessed the association between patient sex and the primary outcome of bystander CPR, and secondary outcomes of bystander naloxone administration, automated external defibrillator (AED) application, and CPR technique, using multivariable logistic regression. Results: Among 3012 included cases, the median age was 40 years (Quartile 1 = 31, Quartile 3 = 50) and 826 (27%) were female. Female sex (compared to male) was associated with a higher odds of receiving bystander CPR (adjusted odds ratio [aOR] 1.2; 95% CI: 1.0-1.5). Female sex was not associated with bystander naloxone administration (aOR 1.0; 95% CI: 0.81-1.3) or AED application (aOR 0.82; 95% CI: 0.48-1.4). Female sex was associated with a higher odds of receiving compression-plus-ventilation CPR versus compression-only CPR (aOR 1.8; 95% CI: 1.0-3.0), although CPR type was frequently not noted. Conclusion: In OHCA cases with evidence of recent non-prescription drug use, female sex was associated with a higher odds of receiving bystander CPR and compression-plus-ventilation CPR. We did not detect an association between sex and bystander naloxone or AED application.
