Study-specific analyses were computed, and then the data from all the studies were pooled conditioning on study. For matched studies, the original matching was preserved, whereas, for unmatched ones, five-year age groups were used for matching. ![]() Conditional logistic regression was used to compute odds ratios. Frequency tables and simple statistics were computed for each variable under study. Data were analysed separately by study center, gender, and the two major histologic types (papillary, follicular). Each of the datasets was checked for outliers and consistency. Of the cases, 79% were classified as papillary thyroid carcinomas, 14% as follicular, 2% medullary, 1% anaplastic, 1% other histologies, and 3% histological type unknown. Results: A total of 2,725 cases (2,247 females and 478 males) and 4,776 controls (3,699 females and 1,077 males) were included in this study. Radiotherapy and, in Japan, exposure to the A-bombs were considered as potential confounding factors. For women, we also analyzed menstrual and reproductive factors and use of female hormones. Data on socio-demographic characteristics, anthropometric measures, smoking and alcohol consumption, history of benign thyroid diseases and of other selected medical conditions and treatments, family history of cancer and of benign thyroid conditions, occupation, residence in endemic goitre areas, and dietary habits were analyzed. Methods: The original datasets were obtained and restructured in a uniform format. Four studies were conducted in the United States (1 each in Washington State, California, Connecticut and Hawaii), 8 in Europe (3 in Sweden, 2 in Norway, 1 in Switzerland, 1 in Italy and 1 in Greece), and 2 in Asia (1 in China and 1 in Japan). This paper describes the major characteristics of the 14 studies included in the analysis, as well as the statistical methods employed. Most importantly, the staff speak individually with each camper to help him grow in self-knowledge and to formulate resolutions for growing in character after the camp.Objective: Because the etiology of thyroid cancer is not well described, we conducted a pooled analysis of all published case- control studies, as well as two identified unpublished studies. Throughout the week, the counselors of each team help the boys to apply principles of leadership and lessons from the virtue talks to concrete situations during the camp. Spiritual activities, such as the Rosary and confession, are also offered. Camper s will also have the opportunity to learn skills such as woodworking and story-telling. In the afternoons, boys compete in various camp-wide activities such as Capture the Flag, Death Valley, Olympics, a Treasure Hunt and Talent Show, and cool off with a swim. Every morning campers attend Holy Mass, compete in football, soccer, dodge ball, and other sports, and attend a talk on a specific virtue. Over the course of the week he attends activities, competes in games, and wins points towards the glorious LCD Cup. Each boy is placed on a team with about 10 other campers.
