Correlation between visit 3/visit 2 individual ratios for sTXB₂ and urinary TXM values. The plot shows the linear correlation (blue line) between the ratios of sTXB₂ and urinary TXM values at visit 3/visit 2 in all patients, according to the randomized treatment (correlation coefficient, r² = +0.12; P < .0001). bid, twice daily; od, once a day; tid, thrice daily. The shaded area represents the 95% confidential interval of the linear regression line.
