    The study evaluated the impact of COMFORT-based nurse-patient communication and respiratory training on methacholine bronchial challenge tests.

  • 2

    The intervention group had a significantly higher first-attempt success rate compared to the control group (75.6% vs. 24.4%, p < 0.001).

  • 3

    In-chamber testing duration was shorter for the intervention group, averaging 11.85 minutes compared to 16.90 minutes for controls (p < 0.001).

  • 4

    Post-procedure anxiety and distress scores were lower in the intervention group, indicating reduced psychological burden during testing.

  • 5

    Mild procedure-related adverse events were less frequent in the intervention group (7.3% vs. 24.4%, p = 0.032), suggesting improved safety.
