Parametric data are group mean ± SEM with statistical analysis by unpaired t test or one-way ANOVA with Dunnett post hoc test. Nonparametric data are group median with Mann-Whitney U test or Kruskal-Wallis with Dunn post hoc test. CSF, cerebrospinal fluid; MNCV, motor nerve conduction velocity; nd, not determined; SNCV, sensory nerve conduction velocity.
*P < 0.05,
**P < 0.01, and
***P < 0.001 vs. STZ or ZDF as appropriate.
