Impact of the COVID-19 pandemic on out-of-hospital cardiac arrest outcomes in older adults in Japan.
Article in Resuscitation plus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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: The coronavirus disease (COVID-19) pandemic has negatively affected access to healthcare and treatment. This study aimed to explore the impact of the COVID-19 pandemic on older adults with out-of-hospital cardiac arrest (OHCA) in Japan, a country with a super-aging society. Methods: This secondary analysis of the All-Japan Utstein Registry included patients aged 65 years and older with bystander-witnessed OHCA between January 1, 2005, and December 31, 2020. Survival outcomes were compared by time period using multivariable logistic regression analyses. The primary outcome measured was the one-month survival rate with neurologically favorable outcomes. Results: Before the COVID-19 pandemic, survival outcomes were steadily improving, and 32,024 patients in 2019 and 31,894 in 2020 were eligible for analysis. The proportions of conventional cardiopulmonary resuscitation and shock by public-access automated external defibrillators were lower in 2020 than in 2019 (6.7% versus 5.7%, Conclusion: In this population-focused, bystander-witnessed study regarding OHCA, the analysis of nationwide registry data revealed that the COVID-19 pandemic was associated with reduced survival among older adults with OHCA in Japan.
