Zangfu zheng (patterns) are associated with clinical manifestations of zang shang (target-organ damage) in arterial hypertension

Table 3 Similarity between descriptions of Chinese medicine patterns and target-organs damage

	Patterns
Target-organs damage	Liver-fire blazing upwards (n = 11)	Kidney-yin deficiency and Liver-yang rising (n = 13)	Obstruction of phlegm and dampness of Heart/Liver/ Gallbladder (n = 10)	Qi and blood deficiency leading to Liver-yang rising (n = 7)	Kidney-yin/yang deficiency (n = 11)
CVD (n = 19)	0.15* [0.19; 0.58]	0.23 [0.19; 0.69]	0.26 [0.17; 0.70]	0.30 [0.15; 0.86]	0.15* [0.19; 0.73]
HD (n = 7)	0.12* [0.13; 0.86]	0.11 [0.11; 0.86]	0.13 [0.13; 0.86]	0.00* [0.07; 0.86]	0.06* [0.12; 0.86]

Jaccard coefficient of similarity between manifestations of patterns and target-organs damage calculated from ZFHD and TODD datasets.
* Values significantly lower than expected at random, P < 0.05. All other values not different to those expected at random were left unmarked. Values in brackets represent critical values of S_J with a probability level of P < 0.05 considering the total number of manifestations present in either of the two patterns being compared and the minimum quantity of manifestations between patterns and target-organs. CVD: cerebrovascular and eye disease; HD: heart disease; KD: kidney disease.
