Results of a Pilot Randomized Placebo-Controlled Trial in Primary and Secondary Raynaud's Phenomenon with St. John's Wort: Detecting Changes in Angiogenic Cytokines When RP Improves
Table 2
Within-group comparisons of patient-reported improvements in the frequency of Raynaudβs attacks and the difference of cytokine levels between pre- and post-treatment. values were calculated using 2-tailed, paired -tests. Data represents mean comparisons of changes in cytokines in those who had more than 50% reduction in frequency (number) of RP attacks compared to those who did not.
