This study compared the accuracy of surveys of probability samples of American adults with surveys of non-probability samples of people who volunteer to do surveys for money or prizes. Data from one Random Digit Dialing (RDD) telephone survey, one Internet survey of a probability sample recruited by RDD, and seven Internet surveys of non-probability samples(More)
BACKGROUND Relatively little information is available in the literature concerning the cost of psoriasis in the United States, and much of that information is out of date. OBJECTIVE The present analyses estimate the direct cost of medical care for psoriasis (including psoriatic arthritis) from a societal perspective among adults in the United States. (More)
INTRODUCTION A multicenter prospective study was designed and implemented to assess the short- and longer-term results and risks associated with radiofrequency (RF) ablation in children. METHODS AND RESULTS Patients recruited for the study were aged 0 to 16 years with supraventricular tachycardia due to accessory pathways or AV nodal reentrant tachycardia(More)
Common single-nucleotide polymorphisms (SNPs) at nicotinic acetylcholine receptor (nAChR) subunit genes have previously been associated with measures of nicotine dependence. We investigated the contribution of common SNPs and rare single-nucleotide variants (SNVs) in nAChR genes to Fagerström test for nicotine dependence (FTND) scores in treatment-seeking(More)
Chronic respiratory diseases are prevalent, disabling, and rank fifth in terms of cost of illness among major disease groups; however, the degree of work loss and lost income is largely unknown. Lost wages in adults with chronic respiratory conditions were calculated from the Survey of Income and Program Participation (SIPP). The National Health Interview(More)
OBJECTIVES To determine the differential cost effectiveness of 2 dosing regimens of bupropion sustained release (SR) in combination with behavioral interventions of minimal intensity (tailored mailings [TM]) or moderate intensity (proactive telephone calls [PTC]) for smoking cessation in an actual practice setting. STUDY DESIGN Open-label, randomized(More)
This study evaluated association between common and rare sequence variants in 10 nicotinic acetylcholine receptor subunit genes and the severity of nausea 21 days after initiating the standard, Food and Drug Administration-approved varenicline regimen for smoking cessation. A total of 397 participants from a randomized clinical effectiveness trial with(More)
UNLABELLED The net benefit (i.e., benefits minus costs) of sustained-release (SR) bupropion for smoking cessation from an employer's perspective has previously been evaluated in clinical trials including frequent, in-person behavioral counseling and manufacturer recommended dosing but not in actual practice settings and lower dosing. OBJECTIVES The(More)
AIMS To examine person-specific urge-to-smoke trajectories during the first 7 days of abstinence and the relationship of trajectory parameters to continuous abstinence, demographics, medication and smoking history. DESIGN Hierarchical linear modeling was used to model person-specific trajectories for urge-to-smoke. SETTING Two university-based smoking(More)
