The aim of the study was to assess the relative effectiveness of cessation, secondhand smoke and other tobacco control television advertisements in promoting quitlines in nine states from 2002 through 2005. Quarterly, the number of individuals who used quitlines per 10 000 adult smokers in a media market are measured. Negative binomial regression analysis(More)
Patient pain drawings were blindly selected from five lumbar spine disorder categories. The drawings were classified by low-back physicians, discriminant analysis, and several computerized artificial neural network configurations. The purpose was to determine the reliability of the patient pain drawing when diagnosing low-back disorders and to delineate the(More)
Eight low-back-pain experts who regularly include pain drawings in their clinical workup were asked to classify 25 drawings. The experts used only the drawings to place cases into one of five broadly defined diagnostic categories: benign disorder, herniated disc, spinal stenosis, underlying disorder, or psychogenic disturbance. The physicians demonstrated(More)
Computerized methods are used to recognize the characteristics of patient pain drawings. Artificial neural network (ANN) models are compared with expert predictions and traditional statistical classification methods when placing the pain drawings of low back pain patients into one of five clinically significant categories. A discussion is undertaken(More)
BACKGROUND Retail stores are the primary medium for marketing cigarettes to smokers in the US. The prevalence and characteristics of cigarette retail advertising and promotions have been described by several investigators. Less is known about the proportion of cigarette sales occurring as part of a retail promotion and about the effects of tobacco control(More)
BACKGROUND Evidence indicates that point of purchase (POP) advertising and promotions for cigarettes have increased since the Master Settlement Agreement (MSA). Retail promotions have the potential to offset the effects of cigarette tax and price increases and tobacco control programmes. OBJECTIVE To describe the trend in the proportion of cigarette sales(More)
A retrospective review of the hospital records of 80 patients undergoing elective lumbar spine surgery was performed, in order to determine the effect of anesthetic technique on various clinical parameters. Forty patients receiving epidural bupivacaine anesthesia were matched with 40 patients receiving general endotracheal anesthesia; these two groups were(More)
Discriminant analysis is applied to 250 quantified low back patient pain drawings to study the ability of a computerized statistical method for classifying novel cases into one of five clinically-significant lumbar spine disorders. Tests on independent data were 46.2 percent (%) correct overall. Benign disorder (55.6%), herniated disc (51.7%), and(More)
Health care practitioners believe that patient education enhances patients' compliance with treatment, their medical outcomes, and their quality of life. This study evaluated an existing method of noncomputerized structured preoperative education delivered by a nurse specialist and implemented and evaluated a computer-assisted instruction (CAI) tool for(More)
We used scanner data on cigarette prices and sales collected from supermarkets across the United States from 1994 to 2004 to test the hypothesis that cigarette prices are positively correlated with sales of cigarettes with higher tar and nicotine content. During this period the average inflation-adjusted price for menthol cigarettes increased 55.8%. Price(More)
