From: The precision of ROTEM EXTEM is decreased in hypocoagulable blood: a prospective observational study
Comparison of the coefficients of variation in different coagulable states. Coefficients of variation (CV) from eight parallel channels for CT, CFT, alpha-angle, and MCF with medians and interquartile ranges. The groups were divided into normocoagulable, hypocoagulable, and hypercoagulable according to the manufacturer’s reference ranges for each of the ROTEM parameters. Mann–Whitney U tests for CT, CFT, and alpha-angle with p-values are outlined in the figure. Kruskal–Wallis and post hoc Dunn’s tests were used for MCF. One alpha-angle value was classified as hypercoagulable and excluded in the analysis. NS: not significant
