Figure 2: Grip strength deficit in GALT-null rats correlates with decreased body mass.
(A) Both male and female GALT-null rats show significantly diminished mean front paw grip strength at 1-month of age when both sexes show growth delay (Supplemental Figure 1, panel E). (B) At 4-months of age, when male but not female GALT-null rats show continued growth delay (Supplemental Figure 1, panel F), only male GALT-null rats show significantly diminished mean front paw grip strength. (C) Normalizing mean front paw grip strength by body mass eliminates any apparent grip strength deficit in 1-month old GALT-null rats. (D) Normalizing mean front paw grip strength by body mass renders grip strength in 4-month-old GALT-null and control rats no longer statistically different. P-values in panels A and C were calculated using Wilcoxon rank sum tests, and in panels B and D, p-values were calculated using t- tests.
