physical dependence on morphine. These correlations are consistent with the hypothesis that some of the same genetic variants affect diverse opioid adaptive traits.Table 1 Correlations between mapped traits OIH MechOIH TFOIH ThermToleranceDependence OIH Mech 10.46*0.58†-0.50*-0.21 OIH TF 10.43*-0.180.24 OIH Therm 1-0.380.11 Tolerance 10.41* Dependence 1Strain-specific trait data related to the chronic administration of morphine was subjected to Pearson correlation analysis. The resulting correlation coefficients are displayed. P values were adjusted using the Benjamini-Hochberg method to control for false-discovery rate [56]. †: adjusted P value < 0.05 *: raw p value < 0.05.
