The effectiveness of the therapy (PASI score).

CCT content	PASI score		Statistical significance of differences	Efficiency (%)
	Before GT	After GT
CCT-3% (𝑛=23)	16.20 (12.70–20.85)	7.80 (6.60–10.70)	𝑃<𝟎.𝟎𝟎𝟏	50.9   (41.9–60.58)
CCT-5% (𝑛=32)	17.10 (14.80–20.60)	6.05 (4.30–7.95)	𝑃<𝟎.𝟎𝟎𝟏	62.7 (52.4–74.0)
Statistical significance of differences	NS	𝑃<𝟎.𝟎𝟓		𝑃<𝟎.𝟎𝟏

The effectiveness of the therapy is expressed as the PASI score; the values are presented as median (lower–upper quartile) because of nonnormal data distribution; 𝑛: number of subjects; 𝑃: Wilcoxon matched-pairs test.
Calculation of the efficiency of the treatment: (100 − [PASI after GT/PASI before GT] × 100).
