Why this differs from similar rows?
Re-analysis of the published He-only P-V data of Speziale et al. (2001), not this study's own KCl/He run data, with a 3rd-order BM EOS.

Evidence from the paper
Furthermore, if the helium-only data of Speziale et al. (2001) are re-analyzed with a third-order Birch-Murnagahn EoS we obtain KT0 = 165(1) GPa and K' = 3.74(7), shown by the filled triangles and dash-dotted line in Figure 3.
