1 · What the graph read from 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.

2 · The registry

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: This study aims to assess the impact of the COVID-19 pandemic on out-of-hospital cardiac arrest (OHCA) incidence, bystander cardiopulmonary resuscitation (CPR), EMS resuscitation attempts and survival across Australia and New Zealand. Method: Data were extracted for all OHCAs patients attended by emergency medical services (EMS) between 2017 and 2021 from the Aus-ROC OHCA Epistry (Epidemiological registry). Logistic regression was used to explore differences between the pre-COVID-19 (January 1, 2017 to March 15, 2020) and COVID-19 (March 16, 2020 to December 31, 2021) periods for bystander CPR, EMS-attempted resuscitation, survival to hospital arrival (event survival) and survival to hospital discharge/30 days. Results: The incidence of OHCA increased during COVID-19 in Australia and New Zealand, although this varied regionally. When compared to the pre-COVID-19 period, COVID-19 was associated with a significant increase in the odds of an EMS-attempted resuscitation in Queensland (adjusted odds ratio (aOR) = 1.19; 95%CI: 1.01-1.40, p = 0.03) and Western Australia (aOR = 1.26; 95%CI: 1.03-1.54, p = 0.02). The COVID-19 period was associated with a decrease in survival to hospital arrival in Australia overall (aOR = 0.91; 95% CI:0.83-0.99, p = 0.04), and by region in Victoria (aOR = 0.74; 95% CI:0.63-0.87, p < 0.01) and Tasmania (aOR = 0.48; 95% CI:0.25-0.91, p = 0.02), and with a decrease in survival to hospital discharge/30 days in Australia (aOR = 0.82; 95% CI:0.70-0.96, p = 0.01), and by region in Victoria (aOR = 0.70; 95% CI:0.54-0.91, p < 0.01) and South Australia (aOR = 0.61; 95% CI:0.37-0.99, p = 0.04). There were no significant changes in survival during COVID-19 in New Zealand. Conclusion: Regional variations were observed with respect to the associations of COVID-19 with resuscitation attempts and OHCA survival.
