Results A total of 34 participants (17 responders, 17 nonresponders) were included. In all participants, for every 1 point increase in the HMW:T-ADP ratio, pain severity increased by 4.11 (CI: 0.44, 7.77; p = 0.028). In responders (n = 17), crude T-ADP levels were reduced at 30 min (11.49 ± 3.7; p = 0.001), 60 min (11.54 ± 3.2; p = 0.001) and 120 min (11.39(More)
