Results of structural equation models with variance explained (R²) for each pathway.

<p>The sign of the correlation is color coded (positive/negative, +/-, black/red) and arrow size is scaled by strength of the standardized path coefficients (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0193305#pone.0193305.s003" target="_blank">S1 Table</a>). Solid paths are significant (p ≤0.05) and dotted paths are non-significant.
