Hakulinen C, Pulkki-Råback L, Virtanen M, et al. Social isolation and loneliness as risk factors for myocardial infarction, stroke and mortality: UK Biobank cohort study of 479 054 men and women. Heart 2018;104:1536–42. doi: 10.1136/heartjnl-2017-312663
In this article, the section entitled Procedures included the following text ‘Loneliness was measured with two questions: “Do you often feel lonely?” (no=0, yes=1) and “How often are you able to confide in someone close to you?” (0=almost daily to once every few months; 1=never or almost never)’.
The latter query should have read ‘(0=almost daily to about once a month; 1=once every few months to never or almost never)’.
