Statistical analysis results of post - pre training differences: NMR body mass, lean mass, fat mass, % lean mass, % fat mass; difference between terminal and pre-training NMR mass at 1W and 2W of endurance training; absolute VO\(_2\)max; relative VO\(_2\)max; and maximum run speed.
PRE_POST_STATS
An object of class data.frame
with 90 rows and 21 columns:
character; the measurement being tested.
factor; the age of the rat at the beginning of the training protocol. Levels: "6M" (Adult) and "18M" (Aged).
factor; the sex of the rat with levels "Female" and "Male".
factor; exercise training group. Either "SED" (sedentary) or the number of weeks of training ("1W", "2W", "4W", "8W").
character; interpretation of the value in the
estimate
column. Either "(post - pre) mean" (mean of the paired
(post - pre) differences) or "signed mean (post - pre) rank" (the signed
mean ranks of the (post - pre) differences).
numeric; the value of the estimate, as described by
estimate_type
.
numeric; the standard error of the estimate.
numeric; lower bound of the 95% confidence interval.
numeric; upper bound of the 95% confidence interval.
character; the type of statistical test. Either "t" (Student's t-statistic) or "W" (Wilcox's W-statistic).
numeric; the value of the test statistic.
numeric; the p-value associated with the statistical test.
numeric; the Holm-adjusted p-value.
logical; TRUE
if p.adj
< 0.05.
character; the statistical model used for testing. Either "lm" (linear regression) or "wilcox.test" (Wilcoxon test).
character; the model formula. Includes the response variable, any transformations, and predictors.
character; the probability distribution and link function for the generalized linear model.
character; if reciprocal group variances were used as weights to account for heteroscedasticity (nonconstant residual variance), this is noted here.
character; if any observations were omitted during the analysis, they are listed here.
