From: Evaluation of vitamin A and E deficiency with severity of SARS-COV-2 disease: a case–control study
Correlation between vitamin A and D-dimer (A), CRP (B), Hb (C), TLC (D) as well as PLT (E). Note: r, correlation coefficient. Vitamin A deficiency showed statistical significant correlation with lower hemoglobin levels (r = 0.222, P < 0.05), lower platelet count (r = 0.485, P < 0.01), higher TLC count (r = -0.444, P < 0.001), higher CRP levels (r = -0.551, P < 0.001), and higher D-dimer levels (r = -0.639, P < 0.001) denoting severity of COVID-19
