Gender Differences in Admissions and In-Hospital Outcomes of Patients With Acute Coronary Syndromes During the Coronavirus Disease 2019 Pandemic.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 The incidence of acute coronary syndromes (ACS) decreased during the coronavirus disease 2019 (COVID-19) pandemic. Few studies have investigated gender differences in ACS admissions and outcomes during pandemics and have presented divergent results. This study aimed to investigate the effect of the COVID-19 pandemic on male and female hospitalizations and in-hospital outcomes in patients presenting with ACS. Methodology We designed a retrograde, single-center trial gathering data for ACS hospitalizations during the lockdown (March 9, 2020, to April 30, 2020) compared with the same timeframe of 2019. ACS hospitalizations were subgrouped as ST-elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina (UA). We calculated the incidence rate ratio (IRR) to compare all-ACS and subgroups for male and female hospitalizations and the risk ratio (RR) to compare overall male/female mortality. Results This study included 321 ACS patients (238 males, 83 females) during the COVID-19 lockdown and 550 patients (400 males, 150 females) during 2019. The IRRs of all-ACS/males/females were significantly lower during the COVID-19 period at 0.58 (95% confidence interval (CI) = 0.44-0.76), 0.59 (95% CI = 0.43-0.75), and 0.55 (95% CI = 0.37-0.74), respectively. The IRR for STEMI was significantly lower among females (0.59 (95% CI = 0.39-0.89)), but not among males (0.76 (95% CI = 0.55-1.08)) The IRR for NSTEMI was not significantly lower, meanwhile it was significantly lower for UA among both males and females. The overall ACS mortality increased during the COVID-19 period (7.4% vs. 3.4%; RR = 2.16 (95% CI = 1.20-3.89)). Important increase was found in males (7.45% vs. 2.5%; RR = 3.02 (95% CI = 1.42-6.44)), but not in females (7.2% vs. 6%; RR = 1.20 (95% CI = 0.44-3.27). Conclusions The admissions of ACS reduced similarly in males and females during the COVID-19 pandemic. The admissions of STEMI reduced predominantly in females. We identified a substantial increase in the overall ACS mortality, but predominantly in males, reducing the differences between males and females. Further studies are necessary to better understand the increase in male mortality during the pandemic.
