Odds ratios (ORs) (and 95% CI) of SARS‐CoV‐2 infection for study variables in multivariate analysis (logistic regression)

Dependent variable: SARS‐CoV‐2 positive PCR test
Independent variables:	OR	95% CI
HCQ	0.51	0.37‐0.70
Male sex	1.11	1.09‐1.14
Age (20‐y increment)	1.06	1.05‐1.07
CCT/immunos.	2.06	1.51‐2.82

Note: Immunosuppressants (treatment with corticosteroids: prednisolone, methylprednisolone, deflazacort, or dexamethasone and/or immunosuppressants: cyclophosphamide, cyclosporine, methotrexate, azathioprine, or mycophenolate mofetil for at least 6 mo). HCQ: at least 2 grams per month, on average. The logistic regression model included 359 476 cases (positive cases: 26 813; negative cases: 332 663) due to missing data.

Abbreviations: CI, confidence interval; CCT, corticosteroids; immunos., immunosuppressants; PCR, polymerase chain reaction; SARS‐CoV‐2, severe acute respiratory syndrome coronavirus 2.
