Why this differs from similar rows?
Cites Wang et al. [1996] quasi-hydrostatic XRD compression result (Table 1); other rows in this comparison table cite different original studies/methods (theory vs. experiment).

Evidence from the paper
in excellent agreement with results, V0 = 45.58 Å3, K0 = 232(8) GPa, K'0 = 4.8 from recent quasi-hydrostatic compression study [Wang et al., 1996]; Table 1: Wang et al. [1996] a0 = 3.572 Å, K0 = 232(8) GPa, K0' = 4.8(3)
