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
Objectives: The study aimed to examine the influence of contextual settings on the complex OHCA intervention outcomes thereby providing evidence to guide managers and policymakers in optimizing implementation strategies. Our secondary analysis of an international multi-site trial examined site-level effectiveness of comprehensive versus basic Dispatcher-Assisted CPR (DACPR) interventions on bystander CPR rates, hypothesizing site-specific variation and declining variability as an early sign. Methods: Using 2009-2018 data from the Pan-Asian Resuscitation Outcomes Study (PAROS), we compared monthly and quarterly trends in BCPR rates at selected PAROS sites before and after the intervention. Interrupted time series analysis was performed using regression of monthly BCPR rates for the pre- and post-intervention periods. Results: Six PAROS sites contributed 37,872 out-of-hospital cardiac arrest (OHCA) cases from January 2009 to June 2018. Comprehensive package sites showed consistent improvement in average monthly BCPR rates, with absolute increases ranging from 4.2 to 30.8 percentage points. Sharper post-intervention increases in DACPR rates were observed, indicated by positive site-wise regression coefficient differences (0.07-0.38). However, some sites experienced an initial post-intervention slowdown of the pre-existing trend. The two Basic package sites also improved their BCPR rates by 9.3 and 25.1 percentage points, though the shorter pre-intervention periods limited meaningful interpretation of the rate of change (0.22 & -0.33). Conclusion: Both intervention packages improved BCPR rates, with most sites showing steeper improvements post-intervention. However, variations in timing and magnitude between sites highlight differing levels of system readiness and implementation rigor. Reduced variability has been observed post-intervention.
