Exposure-response relationship between COVID-19 incidence rate and incidence and survival of out-of-hospital cardiac arrest (OHCA).
Article in Resuscitation plus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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: We aimed to report the epidemiology of OHCA, bystander CPR pattern and other Utstein factors in a region in Hong Kong during the COVID-19 pandemic. In particular, we studied the relationship between COVID-19 incidence, OHCA incidence and survival outcome. Methods: This was a retrospective cohort study that used data from our registry to compare features of OHCA during pre-pandemic (Jan 2018 to Dec 2019), low-incidence pandemic (Jan 2020 to Dec 2021) and high-incidence pandemic (Jan to Mar 2022). We used multivariable logistic regression to identify survival predictors. Results: Incidence of OHCA increased dramatically with surging COVID-19 incidence (65.9 vs 74.2 vs 159.2 per 100,000 population per year, Conclusion: The increase in COVID-19 incidence had an exposure-response relationship with an increased incidence of OHCA and worsened survival outcomes.
