The first result column provides a significance value (F-test) for the trendline between standardized contrasts for body mass and their SD. Significant trends indicate that body mass contrasts are insufficiently standardized and may bias results. The second result column provides a significance value (F-test) for the negative trend between log-transformed body mass and femoral scaling coefficients. The columns Root Value, Lower Limit, and Upper Limit provide the root scaling coefficient for Dinosauria and its upper and lower bounds (95% confidence interval). Significance values for growth rate are for the negative trend between log-transformed growth rate and femoral scaling coefficients. Trends that deviate significantly from 0 at the 5% level are highlighted in bold.
