Table 3:

Magnitude (Magn) of amplitude tremor (as percent modulation) and magnitude of frequency tremor (as percent modulation): group means, standard deviations (SD), F-statistics and P values with and without baseline (BL) covariance adjustment (alpha <0.05). Means include data from Baseline 1 and 2 and Post-test 1 and 2 for each drug phase.
