Comment on: Relapse predictors and serologically unstable condition of IgG4-related disease: a large Chinese cohort: reply

Abstract

Sir, We thank Xie and Zhang [ 1] for their interest in our study [ 2]. They suggested that in Cox regression, the factors with a P-value <0.2 in univariate analysis should be included in the multivariate analysis. In addition, they questioned whether the mix of definite, probable and possible subtypes was representative. Concerning the serologically unstable condition, we came to a point that the serologically unstable condition may not need immunosuppression intensification.
