Fig. 3From: Regulatory T cell frequency, but not plasma IL-33 levels, represents potential immunological biomarker to predict clinical response to intravenous immunoglobulin therapyClinical response to IVIG therapy and its correlation with plasma PGE2. Correlation between the clinical response (MRC score) at different time points (weeks 1, 2, and ≥4) after initiation of IVIG therapy and the fold changes in plasma PGE2 level at week 1. Each symbol represents individual patient. r = Pearson correlation. p = statistical significanceBack to article page
