Results of partial correlation analyses.

Partial correlations of network measures and intelligence controlling for age, years of education and gender. Younger elderly: subjects aged 60 to 74. Advanced elderly: Subjects aged 75 to 85. WAIS-R IQ: The Wechsler Adult Intelligence Scale-revised (WAIS-R). PCC: partial correlation coefficient. Significant partial correlations after Holm-Bonferroni correction: *alpha = 0.05/3 = 0.017, **alpha = 0.05/2 = 0.025, ***alpha = 0.05.

控制年龄、受教育年限与性别后，网络指标与智力的偏相关分析。青年老年组：年龄为60至74岁的受试者。高龄老年组：年龄为75至85岁的受试者。韦氏成人智力量表修订版（Wechsler Adult Intelligence Scale-revised, WAIS-R）智商得分。偏相关系数（partial correlation coefficient, PCC）。经Holm-Bonferroni校正后的显著偏相关：*对应α=0.05/3=0.017，**对应α=0.05/2=0.025，***对应α=0.05。
