Figure 5. Postoperative urine total hexafluorolsopropanol (HFIP; unconjugated HFIP and HFIP-glucuronide) excretion (mean plus/minus SE) in control (n = 10, open bars) and disulfiram-treated (n = 11, closed bars) patients. *Significantly different urine fluoride excretion in disulfiram-treated patients compared to control patients (P < 0.05). Control and disulfiram groups initially consisted of 10 and 11 patients, respectively, but the number of patients remaining (shown in or above the bar) after day 2 decreased because of hospital discharge.
