found that diabetes was associated with severe disease only with borderline significance (pooled OR, 3.12 [95% CI, 1.0–9.75], p = 0.05) and was not associated with ICU admission (2.72 [0.70–10.6], p = 0.15) [ 12 ], whereas Kumar et al. reported a pooled OR of 2.75 (95% CI, 2.09–3.62), p < 0.01, for severe disease, of 1.90 (1.37–2.64), p < 0.01, for death, and of 2.49 (1.98–3.14), p < 0.01, for the combined endpoint [ 25 ].
