  • In the conjunction cell where different stages in the column and the row meet, the first row indicates p values, the second row indicates the designation of statistical significance, the third row indicates 95% confidence intervals. These data show that branch numbers of developing SGNs decrease over time. n.s., not significant. ****p < 0.0001.
