Owing to a production error, several dependent variables were omitted from the part of Table 2 that pertains to Study 1 in the article as originally published. The variables in question are mean diastolic blood pressure, breath rate, C-reactive protein concentration, D-dimer concentration, fasting glucose concentration and plasma potassium concentration. The complete part of Table 2 that pertains to Study 1 is presented here.
Table 2.
Study 1. Repeated measures analysis comparing changes in variables from baseline to 5 days treatment (T1).

SD, standard deviation; mean BP, mean blood pressure; [K+] plasma, plasma concentration of potassium; CRP, C-reactive protein. Figures are expressed as Mean and Standard Deviation. NS, non-significant difference. No patient required ventilation: patients with oxygen saturation less than 92% given oxygen by mask.
