![No association between excessive erythrocytosis and CMS score at 5100 m. (A-C) Individual intravascular volumes of participants categorized into no CMS (CMS−) and CMS (CMS+) with the CMS score including the [Hb] criterion. Erythrocytosis was determined by RBCV measurement. The effect of altitude was assessed with a Kruskal-Wallis test including all participants. Pairwise comparisons using a Mann-Whitney U test with Bonferroni correction were performed and visualized with brackets above the graphs. The effect of CMS at 3800 m or 5100 m was assessed with a Mann-Whitney U test with $P < .01 vs CMS−. Lines indicate median and interquartile range.
