Since the publication of the above paper, the authors have noticed an error in Table 1. The number of MP and MPT patients in ‘IFM 01-01’ are 116 and 113, respectively; thus, the total number of patients listed should be 229 and not 226. This has now been amended, and the correct table is shown below.

Table 1 Trial characteristics

In addition, in the abstract and in the results section, the total number of patients analyzed in all included studies was listed as 1568. It is in fact 1571.

The authors would like to apologize for any inconvenience this may have caused.
