Case fatality rate of zoonotic SARS.CoV2 and associated risk factors in the Libyan population.
Article in Open veterinary journal, 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
Background: Infectious zoonotic viral respiratory diseases have dramatically emerged and reemerged globally, with high socioeconomic and public health impacts. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak was first reported in China as a transmissible disease among animals and humans with great universal public concern. Later, it slipped across the world as a pandemic with a high significant case fatality rate (CFR). Aim: This study was conducted to estimate the CFR and potentially associated risk factors among animals and the Libyan population. Methods: This retrospective cohort study assessed the CFR of coronavirus disease 2019 (COVID-19) and investigated the potentially associated risk factors (socio-demographic data, animal reservoir, household characteristics, and health status) among the Libyan population from July 2020 to January 2021. A total of 3,000 respiratory specimens (nasopharyngeal swabs) were screened by real-time reverse transcription polymerase chain reaction to detect SARS-CoV-2. Descriptive analyses, frequency, and percentage were measured for numerical data and numbers, and rate for qualitative data. The level of the association among variables at the significance level ( Results: The present study reported a variable degree of association with the investigated risk factors included in this study: sociodemographic data, household characteristics, and health status. The overall CFR showed significant differences in vitamin D, Blood group system (ABO), health status, and comorbidity. Conclusion: The CFR seems to have been underestimated; however, our result reported a relatively high CFR in Libya, at least in the surveyed region (targeted population). The risk factors measured in this study potentially significantly influenced the CFR. Among these potential risk factors were animal welfare, vitamin D levels, the ABO system, lymphocyte count (level), and healthy status. In contrast, the results showed that other risk factors were not significantly associated with the CFR. The results highlighted the potential risk of fatalities in the country. A large set of prospective studies is required to enhance our understanding of the CFR associated with zoonotic COVID-19 in Libya.
