Remark 2. Several Razumikihin-type theorems on pth moment exponential stability for stochastic differential equations were developed in [17], by applying their results to stochastic delay differential equations and stochasticallyperturbed equations, the author can generalize several known results. However, the effectiveness of the provided stability condition in [17] is difficult to check in practice due to the construction of Lyapunov function is skillful, and someof the results in their paper are more conservative than ours in some cases
