FACTORS ASSOCIATED WITH COVID-19 RELATED DEATH IN 2020 IN CROATIA: A NATIONWIDE OBSERVATIONAL COHORT STUDY.
Observational study in Acta clinica Croatica, 2025. 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 coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus (SARS-CoV-2) has had a global effect on mortality. Many attempts were made to identify those at the highest risk of death if infected with SARS-CoV-2, yet the relative importance and global generalizability of individual risk factors remain unclear. At the Croatian Institute of Public Health, electronic health data from multiple databases were combined to examine factors associated with COVID-19 related death. Data on 212 615 patients confir med to have COVID-19 by a positive RT-PCR in 2020 were pseudonymously linked to hospital records and 16 150 hospitalized patients were identified. Apart from older age and male sex, major factors associated with an increased rate of mortality among patients hospitalized with COVID-19 were cardiovascular diseases (adjusted HR: 1.20; 95% CI 1.12-1.28); diabetes (adjusted HR: 1.17; 95% CI 1.09-1.25); and chronic lower respiratory diseases (adjusted HR: 1.10; 95% CI 1.02-1.18). This Croatian study used primary care and hospital data to establish factors associated with COVID-19 related death among patients hospitalized with COVID-19. The results of this study provide rigorous evaluation of the previously defined risk factors and offer guidance for further studies that will create prognostic models based on empirical data from 2020.
