"Subjective fatigue score per stimulant and their respective placebo condition. The grey dots represent the individual participants’ scores and the white diamond represents the group mean. *, p &lt; .01"
"Participants received placebo (microcrystalline cellulose) and a single oral dose of one of three stimulants: <b>20 mg of immediate-release methylphenidate</b> or <b>200 mg of modafinil</b> or <b>200 mg of caffeine</b>. We chose these doses because it has been shown for MPH and MOD that they lead to an equivalent dopamine transporter occupancy (Volkow et al. 2009; Volkow et al. 1998) and because in clinical practice and previous studies they have been shown to be equipotent (Franke et al. 2017; Repantis et al. 2010; Theunissen et al. 2009)."
