text: 2.9. Statistical analysis 
  Data are expressed as mean 6 SEM unless otherwise specified, 
  and P values of less than 0.05 were considered significant. Power 
  calculations were performed using G*Power 3.1.9.7.15 A 
  quantitative Venn diagram was created using BioVenn.25 All 
  other statistical analyses were performed in Prism 10 (GraphPad 
  Software, Inc, Boston, MA) or R using paired t tests or 1- or 2-way 
  RM ANOVAs (repeated measures analysis of variance), where 
  appropriate. Normality was assessed by the Shapiro–Wilk test. If 
  ˇS´ıd ´ak or 
  the main analysis of variance effect was significant, 
  Tukey multiple comparisons tests were performed. To compare 
  population distributions of soma cross-sectional area or volume, 
  Kolmogorov–Smirnov tests were performed. 
  
  As a third complementary approach, we applied semiauto- 
  mated volumetric analyses of nuclei size following tissue clearing. 
  In this study, whole DRGs were cleared 4 weeks after SNItrans for 
  nuclei counting in “complete” tissue (Figs. 2E–H). Nuclei were 
  labelled by TDP-43, in line with the study by West et al.,67 and 
  were quantified using Imaris software (Fig. 2F, Video 1). We 
  observed a slight but significant rightward shift in nuclear spot 
  volume population distribution 4 weeks after SNItrans (Fig. 2G). In 
  addition, there was a significant reduction in the number of small 
  but not medium or large nuclear spots, in support of a loss of 
  small-diameter neuron populations (Fig. 2H).
