A. The distribution of patients according to basal D-serine plasma concentrations using 3.5 μM as the cutoff between “high” and “normal” concentrations where the subjects in the Timber-K arm of the are denoted in blue and the subjects in the TIMBER-P arm are denoted in red. B. The changes in the D-serine plasma concentrations at the conclusion of the 40-min intra venous infusion where the subjects receiving a 0.5 mg/kg dose of (R,S)-ketamine (K) are denoted in red and the subjects receiving normal saline (P) are denoted in blue and where basal plasma concentrations of D-serine are indicated by open circles (○) and the 40-min concentrations by filled circles (●).
