Xval, cross-validation; RMSE, root-mean-square error; cAIC, corrected Akaike information criterion; Overall, overall accuracy (%); Pair, pairwise accuracy (%).

Boldface type indicates the model with lowest RMSE and cAIC for each study.

Blue shading indicates cAIC values that are within the cAIC threshold of the lowest cAIC value.
