a strong trendp = 0.05
While no significant correlation between CAG-repeat length and absolute LQ was observed (r = −0.11; p = 0.31; polyserial correlation coeffient: −0.11), a strong trend was recognizable for a correlation between CAG-repeat length and LQ (r = −0.22; p = 0.05; polyserial correlation coeffient: r:−0.22), indicating that in homozygous women longer CAG-repeats had a tendency to be related with stronger left-handedness ( Fig. 3 ).
