Corrigendum to “Media consumption and sleep quality in early childhood: results from the Ulm SPATZ Health Study” [Sleep Medicine 45 (2018) 7–10]

The authors regret that there has been a mislabeling of the variable on book reading. The previously labelled categories “never”, “up to 1h”, and “> 1h/d ” denoted in the methods section should have been labelled “up to 1h”, “1–2h/d”, and “> 2h/d ”, respectively. The same change in labelling of book reading applies to Figure 1 and Table S1 in the online supplement as well as footnote 3 to Table 2. For the electronic media indicators, groups remain as indicated in the methods section and throughout the manuscript.
