Figure 2From: No association of polymorphisms in the serotonin transporter gene with thermal pain sensation in healthy individuals Thermal detection and pain thresholds, divided by triallelic 5-HTTLPR. CDT: cold detection threshold; WDT: warm detection threshold; CPT: cold pain threshold, HPT: heat pain threshold. Boxes: interquartile range, whiskers: 10% and 90% percentiles. No significant differences between groups (p >0.4 Mann–Whitney U-test).Back to article page
