Comparison analysis matching groups for subjective pain levels.

Group activations show P<0.05 False Discovery Rate (FDR) whole brain corrected. The contrast patients>controls show P<0.05 FDR corrected for the volume of activated regions (pain network). Coordinates (mm) are in the standard Talairach space. SII, second somatosensory cortex, SMA, supplementary motor area. No significant findings were obtained in the contrast controls>patients.

各组激活模式经全脑错误发现率（False Discovery Rate, FDR）多重比较校正，显著性阈值设定为P<0.05。患者组与对照组的激活对比（患者组＞对照组）经激活脑区（疼痛网络）体积校正的FDR检验，结果满足P<0.05。坐标单位为毫米，采用标准Talairach空间坐标系。涉及的脑区包括次级躯体感觉皮层（SII, second somatosensory cortex）、辅助运动区（SMA, supplementary motor area）。对照组与患者组的激活对比（对照组＞患者组）未发现显著激活结果。
