Data:

Data from the Missouri Cancer Registry's 1996-2008 database.

 

Cases include all tumors that were reportable under both ICD-O-2 and ICD-O-3 (SEER Behavior Recode for Analysis equal to "Malignant", see http://seer.cancer.gov/behavrecode/index.html).

 

Cancer sites are based on SEER Site Recode ICD-O-3 (1/27/2003) Definition with separate groupings for Kaposi Sarcoma and Mesothelioma (see http://seer.cancer.gov/siterecode/icdo3_d01272003/).

 

    Statistics:

Rates are per 100,000 and age-adjusted in 19 groups (<1, 1-4, 5-9, ..., 80-84, & 85+) to the 2000 US Population (Census P25-1130 standard).

 

The Lower and Upper Limits (LL & UL) of the confidence intervals for the rates are shown in the bar chart.  These confidence intervals (Tiwari, et al. 2006) are 95%.

 

The values in the "SE" column of the table are the Standard Errors of the rates.

 

Each county rate was compared to the state-wide rate by testing if the rate ratio differed from 1 (Tiwari, et al. 2006).  Due to the geographic overlap in the numerator and denominator of the rate ratio, these tests will be more conservative (lower Type I Error rate) than the nominal Type I Error rate of 5%.  The results are reported in the "Sig." column of the table:

"-": no statistically significant difference,

"L": county rate is statistically significantly lower than the state rate (p-value <= 0.05), and

"H": county rate is statistically significantly higher than the state rate (p-value <= 0.05).

       

Case counts, rates, and standard errors are suppressed if the case count was less than 6 to protect patient confidentiality.

 

Note, rates corresponding to a case count of less than 16 are very unstable and especially should not be interpreted without regard to its confidence interval and/or standard error.

 

    Geography:

Missouri has 115 counties (including the City of St. Louis, an Independent City not contained in any county).
