Great that you mentioned the beta values, the coefficients in the tables are in fact unstandardised beta coefficient values, this has been made clearer in the tables. The tables have diet (ind variable) on the left and the dependent variable KS-10 is on the top to indicate that interaction, then this is stratified by gender. I hope this makes more sense now.
The level of reporting of the core assessment instruments and their items, dimensions and subdomains needs to be enhanced.
