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
Aim: Dispatcher-provided cardiopulmonary resuscitation (CPR) instructions are recommended in current resuscitation guidelines. However, the factors influencing whether dispatchers provide such instructions remain unclear. This study investigated the implementation of dispatcher-provided CPR instructions and identified associated factors using a nationwide registry in Japan. Methods: We conducted a retrospective analysis of out-of-hospital cardiac arrest (OHCA) cases registered in the Japanese Association for Acute Medicine OHCA Registry between June 2014 and August 2023. The cases were categorized into two groups according to whether the dispatchers provided CPR instructions. Multivariable logistic regression was performed to identify factors that were independently associated with dispatcher-provided instructions. Results: Among 59,407 eligible OHCA cases, the dispatcher provided CPR instructions to the bystander for 27,414 (46.1%). Multivariable analysis revealed that female sex, a closer bystander-patient relationship, and unwitnessed arrest were significantly associated with a higher likelihood of dispatcher-provided instructions. By contrast, certain non-medical causes, such as traffic accidents, falls, and poisoning, were associated with lower dispatcher-provided instruction rates. Age showed a nonlinear association. Substantial temporal and regional variability was also observed. Conclusion: The likelihood of dispatcher-provided CPR instruction was influenced by a combination of patient, bystander, and system-level factors. These findings underscore the need for standardized dispatcher training and protocols to improve the recognition of OHCA and timely delivery of CPR instructions.
