In order to reduce the dimensionality of the topic incidence file, we further took steps to only include words appeared more than twice in the entire database for the association mining.
The 5-year observed survival curves for women aged 20 years and older were calculated from 1992-2002 for each racial/ethnic group using the incidence case files of Puerto Rico and the SEER 17. Survival curves by racial/ethnic group were estimated using the Kaplan-Meier method [ 21] and differences between survival curves were assessed using the log-rank test [ 22], using SAS 9.1.
Incident data of endometrial cancer for Puerto Rico were obtained from the incidence case file [ 8] from 1992-2003.
Any incidence of file separation within the complex canal system makes retrieval extremely difficult and also renders the root walls highly susceptible to perforations.
In particular, the region IX showed a different pattern characterized by a strong periodicity and a continuous negative trend of incidence (Additional file 1: Figure S1).
The following keywords were combined: "female", "papillomavirus infection", "DNA probes, HPV", "DNA, viral", "genotype", "polymerase chain reaction", "sequence analysis, DNA", "uterine cervical neoplasms", "cervix uteri", "epidemiologic studies", "prevalence", "incidence" (Additional file 1).
In simulation studies, the seasonal pattern of effective migration events was better reconstructed when tip (sequence) sampling was proportional to incidence (Additional file 2: Methods 3.3.2.2), as opposed to when sampling was uniform across time and in different populations (Additional file 2: Methods 3.3.2.1).
The median density of corn acreage in Missouri was lower than the other states and higher densities were associated with lower leukemia incidence rates (Additional file 1: Table S5).
For each province, an approximate seasonal pattern is established based on the number of samples in two-months bins, and a clustering algorithm is used to partition the provinces by their incidence seasonality (Additional file 1: Figure S3).
A correlation of >0.4 was chosen to assess the hypothesis that with respect to the questionnaire, self-reported exercise-related injury was correlated with healthcare provider diagnosis for injuries requiring medical attention or incidence report forms filed by the fitness instructors of the CCAA for injuries not requiring medical attention.
