Do Comorbidities Play a Role in Hand Osteoarthritis Disease Burden? Data from the Hand Osteoarthritis in Secondary Care Cohort
Damman W, Liu R, Kroon FP, Reijnierse M, Huizinga TW, Rosendaal FR, Kloppenburg M. Do comorbidities play a role in hand osteoarthritis disease burden? Data from the Hand Osteoarthritis in Secondary Care Cohort. J Rheumatol 2017; doi:10.3899/jrheum.170208. The classification of knee osteoarthritis (OA), according to the American College of Rheumatology criteria, was incorrectly reported in this article. As a result, the numbers in Table 2 for “generalized OA” and “knee OA,” and the estimates for the association of generalized OA and disease burden, are incorrect. The corrected version of the affected part of Table 2 is given below.
Prevalence of generalized osteoarthritis (OA) in a hand OA population (n = 538) in secondary care.
In addition, some portions of the text are incorrect. The corrected versions:
In the Results section, page 1662, column 2, fifth paragraph: “Forty-three percent (227/526) of patients had knee and/or hip OA.”
In the Results section, page 1664, column 1, third paragraph: “Knee/hip OA was associated with both general and disease-specific burden [adjusted mean difference (95% CI)]: HRQOL −4.2 (−5.6 to −2.8), function 1.3 (−0.2 to 2.7), pain 0.7 (−0.1 to 1.5), and TJC 1.1 (0.2–2.0).”
The incorrect numbers and estimates do not affect the article’s message, other results, or discussion.
