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

### Description

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.

### Format

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

ZBS | |

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.
