Why this differs from similar rows?
Cites Mao et al. [1989] diamond-anvil XRD (no pressure medium, up to 134 GPa, non-hydrostatic; Table 1); other rows cite different original studies/methods.

Evidence from the paper
Table 1: Mao et al. [1989] a0 = 3.567 Å, K0 = 281(4) GPa, K0' = 4.0; The equation of state of CaSiO3 perovskite has been measured over a wide range of pressure (up to 134 GPa) using diamond-anvil X ray diffraction techniques [Mao et al., 1989]

note
non-hydrostatic experiment conducted without pressure medium; previous diamond cell studies gave bulk modulus ranging from 275 to 325 GPa
