Following publication of the original article [1], the authors noticed that the numbers 1–5 in the Methods section under subsection “Health- and work-related questions” were mistakenly interpreted as references.

Health- and work-related questions

“To assess their self-rated general health, the following questions were used: How do you experience your [1] “physical health” [2] “mental health” [3] “social environment” [4] “physical environment” and [5] “work ability”? A seven-point scale with answers ranging from “very poor” to “excellent, cannot be better” was used. In the analyses, the answers were collapsed and coded into: poor (≤3), good [4, 5], or excellent (≥6) according to Larsson et al. [16].”

The original article [1] has been updated.
