The original version of this article unfortunately contains an error in page 567, the third paragraph under Discussion section. The word “Slightly higher” should be “Slightly lower”, instead. The revised paragraph is presented as below:

Slightly lower incidences of transaminase elevations and neutropenia with monotherapy were observed. Overall the safety profiles in patients receiving tocilizumab monotherapy and combination therapy overlapped, consistent with results of a recent double-blind study [9]. A larger study would be needed for an appropriate comparison of rates of uncommon events such as serious infections.
