Table 2 Factors associated with the completeness of fluorescent alcohol-based handrubbing under ultraviolet-light (second year)

From: Using an ultraviolet cabinet improves compliance with the World Health Organization’s hand hygiene recommendations by undergraduate medical students: a randomized controlled trial

  1. Results are expressed as %, except Age as mean (±SD)
  2. p-value: comparison by univariate test between the group with AHR Incomplete application versus the group with AHR Complete application
  3. p’-value: p-value by the multivariate logistic regression
  4. Completeness of AHR handrubbing:
  5. -AHR incomplete application corresponds to the presence of one or more areas without fluorescence on the hands and wrists of the students under UV-light
  6. -AHR complete application corresponds to the absence of areas without fluorescence on the hands and wrists of the students under UV-light
  7. Variables concerning the personal experience with hand hygiene between the first and the second year were collected on the second year as a questionnaire format from each 3rd degree student (see Additional file 2)
  8. Abbreviations: AHR: Alcohol-based handrub, SD: standard deviation; UV: Ultraviolet
