Association of summary statistics features of sound pressure level (SPL) and fundamental frequency (f0) with group label across the 51 LASSO models.

The maximum number that the “association count” field can have is 51. This occurs when that particular variable (row) has a statistically significant effect (p < 0.001, absolute average odds ratios ≥1.10) in each model. Many associations persisted across all models and also tended to agree well on the magnitude of the association. The 95% confidence interval (CI) is from the lowest bound across subsets to the highest bound across subsets.
