It was highlighted that in the original article [1] the data on categorical variables was wrongly arranged in Table 1 and there was an incorrect statement in the fourth paragraph of the Discussion section. This Correction article shows the incorrect and correct statement of paragraph 4 and the correct Table 1.
Table 1.

Incorrect statement
Even though the prevalence rate of hypertension in male (29.1%) was mildly lower than female (32.7%), our finding showed a significantly higher PRAL in the male (25.3 ± 20.2 mEq/d) comparing to the female (19.4 ± 16.7 mEq/d).
Correct statement
Prevalence rate of hypertension in male (32.7%) was mildly higher than female (29.1%) and a significantly higher PRAL in the male (25.3 ± 20.2 mEq/d) was also identified comparing to the female (19.4 ± 16.7 mEq/d).
