The increased periostin levels within the first 6 days were grouped according to the NIHSS scores. (A) NIHSS scores on day 1 after stroke. (B) NIHSS scores on day 6 after stroke. Mild stroke, NIHSS score < 8; moderate-to-severe stroke, NIHSS score ≥8. Differences were compared using the Mann-Whitney U test. ^*p < 0.05, ^**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 represent the 10th and 90th percentiles, respectively.
