Fig. 3 a) Mean difference (95% credible intervals [CIs]) between methylphenidate (MPH) compared with placebo on individual fatigue scores (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-F]) for each patient (circle) and the overall group (square). b) Mean difference (95% CIs) between MPH compared with placebo on individual Wu Cancer Fatigue Scale scores for each patient (circle) and the overall group (square). c) Mean difference (95% CIs) between MPH compared with placebo on individual Edinburgh Depression Scale scores for each patient (circle) and the overall group (square). a–c) Note: the solid black circles designate positive responders, the hollow circles designate nonresponders, and the solid gray circle designates a negative responder.
