Table 2.
Unstandardized and standardized path coefficients, and the standard error of the unstandardized coefficients from the final structural equation model linking cotyledon damage (number of cotyledons removed) in Medicago lupulina to plant biomass, days to flowering, flower number and the fitness components of seed number and seed mass

The P-values are from a one-sample t-test of whether the unstandardized path coefficient differed significantly from zero. The paths described in each section of the table were from the indented variables to the variable above.
