Question 5 of 5
A pilot research study was conducted to compare the association between a new type of dressing and a unit's CLABSI rates. During the six-month period prior to the intervention of the new dressing the unit's CLABSI rate was 2.06 per 1000 central line days. During the 6 months the dressing was trialed, the unit's CLABSI rate was 1.76 per 1000 central line days. The p-value was 0.03. What conclusion can be reached?
Correct Answer: A
Rationale: P-value of 0.03 indicates statistical significance, suggesting an association, not causation.
