Table 6 Impact of comorbidity on heal rate (HR) in the fresh fracture cohort

From: A cohort study of 4,190 patients treated with low-intensity pulsed ultrasound (LIPUS): findings in the elderly versus all patients

  Overall   Heal    Elderly   Heal
Comorbidity Healed Failed Rate Lower CI Upper CI Healed Failed Rate
All fractures 4,032 158 96.2% 95.7% 96.8% 554 28 95.2%
Current smokers 652 35 94.9% 93.3% 96.5% 81 1 98.8%
Diabetes 224 11 95.3% 92.6% 98.0% 110 4 96.5%
Hypertension 188 7 96.3% 93.6% 99.0% 83 2 97.6%
Vascular insufficiency 107 5 95.5% 91.7% 99.4% 56 2 96.6%
Osteoporosis 80 5 94.1% 89.1% 99.1% 57 5 91.9%
Cancer 77 4 95.1% 90.3% 99.8% 50 2 96.2%
Cardiovascular disease 60 2 97.2% 93.3% 100.0% 54 2 96.4%
Alcoholism 68 3 95.8% 91.1% 100.0% 10 0 100.0%
Renal disease 44 1 97.8% 93.5% 100.0% 11 1 91.7%
Rheumatoid arthritis 36 4 90.0% 80.7% 99.3% 21 3 87.5%
  1. The overall heal rate (HR) includes all patients, even if they have comorbidities or are older than age 60. Then various comorbidities are broken out, for the entire fresh fracture cohort overall, and for the elderly cohort (≥60 years of age) specifically. Bolded HR numbers are above the CI associated with “All fractures.” Italic HR numbers are below the CI associated with “All fractures.” In the “Elderly” group, bolded HR numbers are above the CI for the corresponding fracture in the whole cohort, while italic HR numbers are below the CI for the corresponding fracture in the whole cohort. Elderly HR is comparable to the HR of the overall sample.
