Association of <i>KCNJ6</i> haplotypes with postoperative analgesia.

Association of the haplotype composed of the G-1250A/A1032G SNPs with (A) the frequency of analgesic administration in all patient subjects or (B) the total dose of analgesics administered during the 24 h postoperative period in female patient subjects. Frequency, haplotype frequency; Beta, regression coefficient; R2, coefficient of determination; F, F statistic; P, crude P value; Pa, adjusted P value for multiple testing. †P<0.05, *Pa<0.05.
