Analysis of 7,807 patients finding that low vitamin D levels are correlated with increased risk of cases and hospitalization. Adjusted odds ratio OR for sufficient vitamin D level for cases 0.69, p < 0.001, and for hospitalization 0.51, p = 0.061.
risk of hospitalization, 46.4% lower, RR 0.54, p = 0.06, high D levels 79, low D levels 703, odds ratio converted to relative risk, >30ng/mL.
risk of case, 28.4% lower, RR 0.72, p < 0.001, high D levels 1,139, low D levels 6,668, odds ratio converted to relative risk, >30ng/mL.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
