Correction to: Measuring hygiene competence: the picture-based situational judgement test HygiKo (BMC Medical Education, (2021), 21, 1, (410), 10.1186/s12909-021-02829-y)

Following publication of the original article [1], the authors identified and would like to correct: The explaining text below the sample vignette incorrectly reads „Fig. 2 Person ability (top) and item parameter (bottom) distribution for the HygiKo-SJT “instead of „Fig. 1 Sample item “and vice versa. The correct descriptions to Figs. 1 and 2 are: - „Figure 1 Sample item “(page 4 of 8) - “Figure 2 Person ability (top) and item parameter (bottom) distribution for the HygiKo-SJT “(page 6 of 8) The original article has been corrected.
