  1. Data are based on means of N measurements (of a total of 2669) for 312 subjects over stated exposures to lithium treatment
  2. Not shown are data for white blood cell counts (WBC), which did not change appreciably (initital: 7.29, final: 7.59 × 10–3 per µL)
  3. BMI (body-mass index [kg/m2]), BUN (blood urea nitrogen [mg/dL]), creatinine [mg/dL], eGFR (estimated glomerular filtration rate for creatinine [mL/min/1.73 m2]), glucose (not necessarily fasting [mg/dL]), WBC (white blood cell count [thousands/µL])
  4. aValues differ significantly from baseline measure, based on Tukey–Kramer post hoc tests comparing each exposure-interval to baseline values
