Brain cancer in males in Navarre, Spain, 1988-1994.


This data set contains the male mortality due to brain cancer in the 40 basic health zones (BHZ) in Navarre over the period 1988-1994, and the neighborhood structure of the BHZ in Navarre. In addition, the data set also includes information about the location of the BHZ, the expected cases, the Standardized Mortality Ratio (SMR), relative risk estimates and 95% confidence intervals.




brainnav: A SpatialPolygonsDataFrame with 40 polygons representing the basic health zones (BHZ) in Navarre, and the following information about each BHZ:

Basic Health Zone Code NAME Name
OBSERVED Number of observed brain cancer cases in males
EXPECTED Number of expected brain cancer cases in males. They are computed using indirect age-standardization using Navarre as a standard population.
RISK Relative Risk Estimates
RISKLL Relative 95% confidence interval, lower limit
RISKUL Relative 95% confidence interval, upper limit
SMR Standardized Mortality Ratio (OBSERVED/EXPECTED)
x x coordinate
y y coordinate

brainnavnb: A neighbor (nb) object which contains the index numbers of the neighbors of each BHZ.
