Comparisons of propensity-score matched ICG and non-ICG for
OHH-related outcomes
A total of 198 propensity-score matched pairs were successfully
identified between the ICG and non-ICG. The data collected on
demographics, occupation, and lifestyle were compared to balance between
the matched ICG and non-ICG (Table 2). The matched ICG was associated
with doubled incidence of body pain when compared to the matched non-ICG
(56.6% vs. 24.2%, p<0.001). The comparisons showed that
cardiologists in ICG had significantly higher incidence of neck pain
(29.8% vs. 11.6%, p<0.001), shoulder pain (33.3% vs.
14.1%, p<0.001), back pain (45.5% vs. 14.1%,
p<0.001), buttock pain (4.0% vs. 0.5%, p<0.046),
knee pain (17.7% vs. 3.0%, p<0.001), thigh pain (7.6% vs.
1.0%, p=0.004), calf pain (10.6% vs. 1.0%, p<0.001), ankle
pain (8.1% vs. 2.0%, p=0.010) and foot pain (5.1% vs. 0.0%,
p=0.031). No significant differences were identified for the verbal pain
rating scale, the incidence of severe pain, pain treatment rate and sick
leave days due to pain in the last five years. Interventional
cardiologists had higher incidence of at least one comorbidity (36.4%
vs. 11.2%, p<0.001) and specific comorbidities including bone
and joint diseases (21.7% vs. 8.6%, p<0.001), cataract
(3.5% vs. 0.0%, p=0.039) and anxiety (8.1% vs. 2.5%, p=0.029). The
OHH-related outcomes are summarized in Table 3.
