Correction of Units of Measure in a Table and the Text

In the Original Investigation titled “Association of Cardiovascular Outcomes With Masked Hypertension Defined by Home Blood Pressure Monitoring in a Japanese General Practice Population,” published online May 23, 2018, and in the July issue of JAMA Cardiology,¹ incorrect units of measure were given in Table 2 and in corresponding text in the Results section. In Table 2, the first 2 rows of data for stroke events should have appeared in a single row, with the variable identified as “Stroke events, No. (No. per 1000 person-years) [95% CI]” and the data given as “8 (1.7) [0.9-3.4]” for the controlled blood pressure (BP) group, “3 (1.3) [0.4-3.8]” for the white-coat hypertension group, “18 (5.4) [3.4-8.5]” for the masked hypertension group, and “45 (6.9) [5.2-9.3]” for the sustained hypertension group. Likewise, the first 2 rows of data for coronary heart disease (CHD) events should have appeared in a single row, with the variable identified as “CHD events, No. (No. per 1000 person-years) [95% CI]” and the data given as “25 (5.4) [3.6-7.9]” for the controlled BP group, “9 (3.8) [2.0-7.3]” for the white-coat hypertension group, “13 (3.9) [2.3-6.6]” for the masked hypertension group, and “30 (4.6) [3.2-6.6]” for the sustained hypertension group. In the Results section of the text, the third sentence of the second paragraph should have read as follows: “The masked hypertension group had a higher incidence rate of stroke events compared with the controlled BP group (5.4 per 1000 person-years; 95% CI, 3.4-8.5 vs 1.7 per 1000 person-years; 95% CI, 0.9-3.4).” This article was corrected online.
