Why this differs from similar rows?
Table 2 cites Ref. 25 (Sinogeikin & Bass), single-crystal Brillouin scattering to 18.6 GPa; sibling row cites Ref. 37, a first-principles theoretical result.

Evidence from the paper
Table 2: Ref. 25* (0–18.6 GPa): K0S = 163.2(1.0) GPa, K'0S = 4.0(1), K''0S = -0.04(2) GPa^-1, G0S = 130.2(1.0), G'0S = 2.4(1), G''0S = -0.04(2). '*Elastic moduli were fit to third- or fourth-order Birch–Murnaghan equations of state.'
