Mortality Assessment in Patients with Cardiovascular Disease and COVID-19: A Systematic Review and Meta-Analysis.
Synthesis in International journal of molecular sciences, 2026. 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
The COVID-19 pandemic has had a profound impact on global health, especially among patients with cardiovascular disease (CVD) and the existence of additional conditions such as diabetes (DM), hypertension (HT), and chronic kidney disease (CKD) can have a significant impact on survival rates. The aim of this study was to determine the mortality rate in patients with CVD and the impact of other comorbidities on the death of patients with COVID-19. This systematic review was conducted using PubMed, EMBASE, and Google Scholar databases from August 2020 to June 2025. Inclusion criteria were patients with cardiovascular disease and associated comorbidities during the COVID-19 pandemic. Article selection was limited to articles published in English and Polish. Statistical analysis using a random-effects model was performed using STATA software. Heterogeneity between studies was examined, and a funnel plot for publication bias was generated. The higher mortality rates (OR = 3.00, 95% CI: 2.06-4.38) for patients with cardiovascular disease were observed. In the group of patients with comorbidities such as hypertension and diabetes mellitus the risk of death was also determined and for HT was OR = 1.94, 95% CI, 1.50-2.52 and for DM OR = 2.17, 95% CI: 1.64-2.86. The mortality in the chronic kidney disease group was higher than for HT and DM (OR = 3.91, 95% CI: 2.50-6.10). The risk of death is three times higher for patients with COVID-19 and CVD. High mortality risk is also linked to diabetes and hypertension but for chronic kidney disease patients increased up to four times.
