Scatter plots for platelet recovery and yield of selected 4 conditions after the second centrifugation step. a Percent platelet recovery relative to PRP1 and (b) yield expressed as fold increase relative to whole blood. Data are presented by groups, the line represents the median of the group; error bars represent the interquartile range. Asterisk (*) indicates a recovery or yield significantly different (P < .05) between the two groups. Condition 5, 1000 g, 15 min; condition 8, 1500 g. 15 min; condition 9, 1500 g, 20 min; condition 10, 3000 g, 10 min
