It is shown that the ratio $\\frac{T_cS_c}{Q_c}$ is universal while $\\frac{T_cr_c}{Q_c}$ is not. This finding is quite interesting considering the former observation that both the $T-S$ graph and $T-r_+$ graph exhibit reverse van der Waals behavior. It is also worth noting that the value of $\\frac{T_cS_c}{Q_c}$ differs from that of $\\frac{P_cv_c}{T_c}$ for $P-V$ criticality. Moreover, we discuss universal ratios for the $P-V$ criticality and $Q-\\Phi$ criticality.
