^aNot significant as the calculated values of 𝜒² were less than the table values at all probability levels (90%, 95%, and 99%).
^bSignificant at all probability levels (90%, 95%, and 99%).
The data responses lines would fall within 95% confidence limits, and thus the model fits the data adequately. UCL-LCL*: upper confidence limit and lower confidence limit. CSTM indicates combined tincture of Capparis decidua, coconut oil, terpene oil, glycerol, elemental sulphur, and liter water.
