  1. aFrom the mean platelet concentration of 230.79 ± 41.48 × 103 cell/μl before centrifugation. Statistical analyses were performed using one-way analysis of variance comparing with the optimal centrifugation force of 900 xg; data expressed as mean ± standard deviation. g = gravitational force. *p < 0.05, **p < 0.01, and ***p < 0.001 in post-hoc tests
