Determining population-specific risk factors for COVID-19 susceptibility and severity to inform future individual-level integrated risk scoring.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
objectivesAcute respiratory tract infections (ARI), including COVID-19, are a significant global health challenge with pandemic potential. Understanding factors influencing ARI susceptibility and severity in different populations is crucial for pandemic preparedness and mitigation. We investigated epidemiological risk factors for COVID-19 susceptibility and severity in the Israeli population.
methodsParticipants who took a COVID-19 PCR test between July 2021 and August 2022 completed an online survey including demographics, comorbidities, infection and vaccination status. We identified factors associated with SARS-CoV-2 infection and disease severity using logistic regression and compared our results with the global literature.
resultsWe included 2128 participants. Of these 823 participants were tested positive for SARS-CoV-2. Individuals without COPD and BMI > 30 had higher infection odds (aOR = 6.21, 95% CI:1.42-27.25 and aOR = 1.54, 95% CI:1.02-2.32; respectively). High school-level education was associated with increased susceptibility and severity compared to higher education (aOR = 1.55, 95% CI:1.1-2.18 and aOR = 2.80, 95% CI 1.62-4.86; respectively). Hospitalization was associated with older age (p < 0.001). Vaccination with 3 doses significantly reduced infection and hospitalization risk compared to unvaccinated (aOR = 0.024, 95% CI:0.016-0.04 and aOR = 0.37, 95% CI: 0.17-0.81; respectively, p < 0.05). Compared to Arab participants, Jewish ones were less likely to be infected (aOR = 1.48, 95% CI:1.02-2.15, p < 0.05).
conclusionsIdentified risk factors are consistent with meta-analyses of studies from other countries. Similar to other countries, minority groups were found to be at higher risk, therefore risk models predicting ARI susceptibility and severity have to take this into account.
