Table 2 Non-invasive break-up time (NIBUT) and self-reported break-up time (SBUT) measured in seconds among men and women (18-67 years) in three exposure groups related to an explosion causing environmental pollution

From: Can air pollution affect tear film stability? a cross-sectional study in the aftermath of an explosion accident

  1. *UI = Unexposed inhabitants far from the explosion area
  2. *EI = Exposed inhabitants near the explosion area
  3. *EW = Exposed workers at the explosion area
  4. † Significant differences between workers and inhabitants near pollution and also between workers and inhabitants far from pollution, Wilcoxon-Mann-Whitney-test, with exact p-values; p = 0.001 for both comparisons.
