Boxplots showing perfusion measures at normal temperature and during cold challenge, S-HAQ scores, RCS and P-VAS scores. (A) Boxplots showing perfusion measures at baseline, week 1 and week 12 at normal temperature. Black boxes represent ambrisentan and gray boxes represent placebo. The bottom and top of the boxes represent the 25th and 75th percentiles, respectively; the band within the box is the median, and the ends of the whiskers are the minimum and maximum of all the data in that group; the square within the box is the mean. The dots on the left of each boxplot represent perfusion measures from individual subjects. (B) Boxplots showing perfusion measures at baseline, week 1 and week 12 during cold challenge. (C) Boxplots showing S-HAQ scores at baseline, week 1 and week 12. (D) Boxplots showing RCS at baseline, week 1 and week 12. (E) Boxplots showing P-VAS scores at baseline, week 1 and week 12. P-VAS, Pain-Visual Analog Score; RCS, Raynaud Condition Scale; s-HAQ, Scloderma-Health Assessment Questionnaire.
