Retrospective survey based analysis of 2,148 COVID-19 recovered patients in Jordan, showing no significant differences in the risk of severity and hospitalization with vitamin A prophylaxis.
risk of hospitalization, 21.2% lower, RR 0.79, p = 0.40, treatment 15 of 144 (10.4%), control 204 of 2,004 (10.2%), adjusted per study, odds ratio converted to relative risk, multivariable.
risk of severe case, 20.8% lower, RR 0.79, p = 0.36, treatment 17 of 144 (11.8%), control 243 of 2,004 (12.1%), adjusted per study, odds ratio converted to relative risk, multivariable.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

The COVID-19 pandemic has caused a global public health emergency. Nutritional status
is suggested to be related to the severity of COVID-19 infection. Herein, we aimed to explore the
impact of using vitamin and mineral supplements prior to COVID-19 infection on disease severity
and hospitalization. In addition, the prior use of aspirin as an anticoagulant on the disease severity
was investigated. A cross-sectional, self-administered survey was conducted between March and
July 2021. Recovered COVID-19 individuals (age ≥ 18 years, n = 2148) were recruited in the
study. A multivariate logistic regression was used to evaluate the associations of supplements and
aspirin use with COVID-19 disease severity and hospitalization status. Among the participants,
12.1% reported symptoms consistent with severe COVID-19, and 10.2% were hospitalized due to
COVID-19. After adjustment for confounding variables (age, gender, BMI, cigarette smoking
status, and the number of comorbidities), the multivariate logistic regression model showed that
the consumption of vitamin D supplements prior to COVID-19 infection was associated with a
significant decrease in disease severity (OR = 0.68, 95% CI 0.50 - 0.92; P = 0.01), and a lower risk
of hospitalization (OR = 0.64, 95% CI 0.45 - 0.89; P = 0.01). On the other hand, there were no
significant differences in the frequencies of severe illness and hospitalizations with the
