From: Knowledge about infections is associated with antibiotic use: cross-sectional evidence from the health survey Northern Ireland

    Odds of self-reported antibiotic use in the past 12 months
  Model‡   Unadjusted Adjusted
  Statements regarding knowledge about infections and antibiotic resistance   OR (95% CI) P OR (95% CI) P
1 Colds and flus should be treated with an antibiotic Incorrect 1.00 (ref)   1.00 (ref)  
Correct 1.15 (0.95–1.40) 0.156 1.01 (0.76–1.33) 0.967
2 Antibiotics are used to treat bacteria Incorrect 1.00 (ref)   1.00 (ref)  
Correct 1.53 (1.32–1.78) < 0.001 1.61 (1.38–1.88) < 0.001
3 Once you start to feel better, you should stop taking the antibiotic Incorrect 1.00 (ref)   1.00 (ref)  
Correct 1.33 (1.08–1.63) 0.007 1.15 (0.87–1.53) 0.335
4 Chances of resistant bacteria increase if you take antibiotics when you don’t need to. Incorrect 1.00 (ref)   1.00 (ref)  
Correct 0.99 (0.86–1.14) 0.909 1.03 (0.89–1.20) 0.653
5 Chances of resistant bacteria increase if you don’t finish the course. Incorrect 1.00 (ref)   1.00 (ref)  
Correct 1.20 (1.04–1.38) 0.011 1.19 (1.03–1.37) 0.021
6 Diseases such as tuberculosis, pneumonia and meningitis are becoming more difficult to treat, as drug-resistant bacteria do not respond to antibiotics and continue to cause infection Incorrect 1.00 (ref)   1.00 (ref)  
Correct 0.95 (0.83–1.10) 0.514 1.03 (0.89–1.19) 0.728
