A Randomized Trial of Chinese Diaoshi Jifa on Treatment of Dizziness in Meniere’s Disease

Table 2

Changes in dizziness handicap inventory (DHI) score in the participants.

DHI score	Diaoshi Jifa group (𝑁=16)	Control group (𝑁=10)	Between-group difference (95% CI)	𝑃
Baseline	63.88±19.94	54.36±17.97	−9.51 (−24.98, 5.96)	0.217
After treatment	10.25±9.77	49.6±20.50	39.35 (24.20, 54.50)	<0.001*
Within-group difference (95% CI)	−53.63 (−42.87, −64.38)	−6.80 (−0.87, −12.73)
𝑃	<0.001**	0.029**

Plus–minus values are means ± SD. The paired 𝑡-test was used for within-group comparison, while independent 𝑡-test was used for between-group difference. *Significantly different from the control group (𝑃<0.01). **Significantly different from the baseline (𝑃<0.05).
