Spearman item-scale correlations and scaling success rate of the CCMQ.

	Baseline (n = 1080)
CCMQ diagnosis	Item-scale correlation	Scaling success rate†
(1) Gentleness	0.377–0.686	100%
(2) Qi-deficiency	0.433–0.717	87.5%
(3) Yang-deficiency	0.517–0.811	85.7%
(4) Yin-deficiency	0.475–0.701	100%
(5) Phlegm-wetness	0.531–0.679	87.5%
(6) Wetness-heat	0.563–0.666	100%
(7) Blood-stasis	0.460–0.681	85.7%
(8) Qi-depression	0.488–0.820	85.7%
(9) Special diathesis	0.488–0.712	100%

All item-scale Spearman correlations were significant (P < 0.001) for two items.

^†Scaling success means the item and hypothesized-scale correlation was higher than all items and competing-scale correlations. This rate was the proportion of total number of comparisons for all the items in each scale that was successful.
