Results:
PVT
This study revealed statistically significant effects of caffeine and
modafinil compared with placebo on all endpoints, except for VigTrack mean
tracking error. PVT results were less impaired 2 h after administration,
followed by VigTrack parameters and SSS scores 2 h thereafter. Compared with
caffeine, modafinil significantly improved PVT and SSS scores at 8 h after
administration.
