Results of Spearman correlation tests. Correlation between reciprocal titres from EIAs and cytotoxicity tests (A), as well as correlation between MICs and MTCs of EOs (B) was determined for the 24 tested B. thuringiensis isolates. Pairs with positive correlation coefficients are shown, which tended to increase together. R: correlation coefficient. *: significant correlation (p-value ≤ 0.05). ns: not significant.
