Confusion matrix of the 20‐chewing stroke MAT and found food consistency thresholds

Expected/answered MAI range	Solid and soft N (%)	Only soft N (%)	Neither solid nor soft N (%)
<20	113 (51.5%)	16 (29.6%)	7 (15.6%)
20 ≤  MAI <24	78 (35.5%)	22 (40.8%)	11 (24.4%)
24≤	29 (13.1%)	16 (29.6%)	27 (60.0%)
Total	220	54	45

MAI, Mixing Ability Index; Soft and solid: reported “Unlikely” to have problems with solid or soft food types; Only soft: only “Likely” to have problems with solid food types; Neither solid nor soft: reported “Likely” to have problems with both solid and soft food types.

The italic values represent the proportion of subjects of whom the reported chewing ability and chewing performance corresponded with the found thresholds for the MAI (true positives).
