Key markers
The horizontal dashed line is the sleep threshold for the solid sleep-disturbance curves. Above it, sleep disturbance is more likely. Below it, meaningful sleep disturbance is less likely. Dotted overlays show modeled pharmacologic effect. Dashed overlays show estimated plasma curve shape. Value boxes estimate blood levels in typical units, not measured lab values. For caffeine, the sleep-disturbance curve intentionally has a longer tail than the effect curve.
