Spatial redistribution of contracting blood clots. Dot-plots showing relative volume fractions of the outer layer (A) and inner portion (B) in the blood clots at increasing extents of contraction. If the boundary was not distinct, the borderline between the outer and inner layers was drawn through the middle of the transition zone. Each dot (n = 54) represents a volume fraction measured for an individual blood clot from 9 identically stained histological slides obtained for clots from 9 independent blood samples and stained with 2 techniques. Results are presented as a median with interquartile range. Statistical analysis was performed using the Friedman test with the correction for multiple comparisons and the false discovery rate with a 2-stage step-up method of Benjamini, Krieger, and Yekutieli.
