According to eTable 7 in their article, all-cause mortality decreases with increasing sodium intake: quintile (Q)1, 699; Q2, 509; Q3, 450; Q4, 372; and Q5, 240 (based on single 24-hour dietary recall). Remarkably, the adjustments performed by Yang et al1 not only attenuated this trend but reversed it. This may be because Yang et al, in contrast to the majority of similar studies, did not adjust for potassium.
