However, the decitabine effect was not significant, and the overall shock effect was only marginally significant ( F (1,3) = 7.90, P < 0.05 one-tail in an ANCOVA with the change in siphon withdrawal as the covariate) and decitabine did not block it ( F [1,3) = 8.08, P < 0.05 one-tail versus no shock).
