In one study of sodium intake and cardiovascular disease, researchers found a statistically significant association between high sodium intake and the prevalence of hypertension among normal-weight subjects. The prevalence of hypertension in the group with the lowest sodium intake was 19.8 percent; the prevalence of hypertension in the group with the highest sodium intake was 20.5 percent. What do these data suggest?

While there was a statistically significant association between high sodium intake and prevalence of hypertension, the difference in prevalence between the lowest and highest sodium intake groups was less than 1 percent. This suggests that while the finding is statistically significant, the practical importance may not be significant enough to draw strong conclusions or make significant recommendations based solely on this study.
