  • *For group 0, values for ‘without PN’ and ‘with PN’ refers to the study periods before 1 April 2013 and after 1 April 2013, respectively.

  • †For subgroup analysis, level of statistical significance at p<0.017 after Bonferroni correction for multiple comparisons.

  • PN, Physician Navigator; Pt/hr, number of patients treated per hour; TAT, turn-around time.
