Fig. 2From: Performance of point-of-care international normalized ratio measurement to diagnose trauma-induced coagulopathyScatter plot of point-of-care INR values (POC-INR, Y-axis) against laboratory INR measurements (lab-INR, X-axis) for the 98 patients. The correlation between these values was weak with a Pearson’s coefficient equal to 0.44 [95% CI 0.27–0.59]. The dash-line represents the ideal linear relationship between the two methodsBack to article page
