Errors were discovered concerning the published equation coefficients of Yang and coworkers [Fluid Phase Equilibria 445 (2017) 1-6] for mathematically describing the solubility behavior of cytarabine in water, methanol, ethanol and cytarabine with the NRTL model and Wilson model. Larger differences were found between our back-calculated data and those reported in the authors' published paper. In addition, the parameters of the two equations were re-analyzed.
