Association of a smartphone-based CPR assistance system with prehospital outcomes in out-of-hospital cardiac arrest: a pre-post observational study in Bangkok.

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: Out-of-hospital cardiac arrest (OHCA) remains a major public health challenge. Smartphone-based systems may facilitate early bystander response; however, their real-world associations with patient outcomes following implementation within emergency medical service (EMS) systems remain uncertain. Objective: This study aimed to evaluate the association between system-level implementation of the MySOS application and prehospital and clinical outcomes among patients with OHCA in Bangkok. Methods: We conducted a retrospective uncontrolled before-after observational study of patients with OHCA in Bangkok, Thailand, between December 2022 and May 2024. Patients were classified according to the pre- and post-implementation periods of the MySOS application. Inverse probability of treatment weighting (IPTW) and weighted multivariable regression were used to account for measured differences between the study periods. Given the temporal definition of exposure and absence of confirmed patient-level application use, findings were interpreted as associations rather than causal effects. Results: Among 615 patients, 340 (55.3%) were included in the pre-implementation period and 275 (44.7%) in the post-implementation period. The post-implementation period was associated with a higher probability of return of spontaneous circulation (ROSC) (adjusted RD 6.28%, 95% CI 1.69-10.86; Conclusions: The post-implementation period of the MySOS system was associated with a higher probability of ROSC, but not with improved longer-term survival outcomes. These findings should be interpreted cautiously because of the uncontrolled before-after design, residual baseline imbalance, potential temporal confounding, and the absence of patient-level data confirming actual application use. Further prospective studies incorporating direct measures of MySOS activation and utilization are warranted.
