The one-fifth of people consuming the most potassium relative to sodium were 14% less likely to die from any cause during a 24 year follow-up than the one-fifth of people consuming the least potassium relative to sodium.
Top one-fifth consuming 77% as much potassium as sodium
The one-fifth of people consuming the most potassium relative to sodium consumed 77% as much potassium as sodium.
To say this another way, the one-fifth of people consuming the most potassium relative to sodium consumed closer to an equal amount of potassium and sodium.
Bottom one-fifth consuming 36% as much potassium as sodium
The one-fifth of people consuming the least potassium relative to sodium consumed only 36% as much potassium as sodium.
To say this another way, this group consuming the least potassium relative to sodium consumed nearly 3 times as much sodium as potassium.
