TriNetX PSM retrospective 10,935 COVID-19 patients, showing higher mortality with zinc deficiency.
risk of death, 70.8% lower, HR 0.29, p = 0.005, high zinc levels (≥70µg/dL) 10 of 1,447 (0.7%), low zinc levels (<70µg/dL) 20 of 1,447 (1.4%), inverted to make HR<1 favor high zinc levels (≥70µg/dL), Kaplan–Meier.
risk of death/hospitalization, 27.3% lower, HR 0.73, p = 0.03, high zinc levels (≥70µg/dL) 81 of 1,447 (5.6%), low zinc levels (<70µg/dL) 107 of 1,447 (7.4%), NNT 56, inverted to make HR<1 favor high zinc levels (≥70µg/dL), Kaplan–Meier.
risk of hospitalization, 17.9% lower, HR 0.82, p = 0.21, high zinc levels (≥70µg/dL) 74 of 1,447 (5.1%), low zinc levels (<70µg/dL) 87 of 1,447 (6.0%), NNT 111, inverted to make HR<1 favor high zinc levels (≥70µg/dL), Kaplan–Meier.
