PCA 1–3 are the first three dimensions obtained from our analysis. Beside the typical PCA statistics, correlation score with success-rate are indicated for each dimension and with a combined r² and p-value in the upper part of the table. Percental contributions of male traits to PCA dimensions are listed in the lower part of the table.
