Serum periostin levels in controls and patients at different time points. (A) Comparison of the periostin levels in 108 controls and 162 patients. (B) Comparison of periostin levels on days 1 and 6 after ischaemic stroke (134 patients). (C) Comparison of periostin levels on day 6 and the 4th week after stroke (46 patients). Student’s t-test (A) or the Wilcoxon signed-rank test (B,C) was used to assess differences. ^**p < 0.01. Boxes represent IQRs, with horizontal lines representing the medians, the lower and upper whiskers representing the 25th and 75th percentiles, and the error bars extending below and above the boxes representing the 10th and 90th percentiles, respectively.
