Help text: Standardised registration ratio for breast cancer

Methodology:

Indirectly age-sex standardised ratios (number of new cases as a percentage of expected new cases), calculated relative to England.

Expected number of new cases of breast cancer (ICD10 C50) calculated by applying age-specific registration rates for England in the latest 5 years to each area's population.

SRRs calculated by dividing the observed total number of new cases in the area by the expected number and multiplying by 100.

Note, due to incomplete or incorrect postcodes, the following cases are not included for all geographic levels. Where it was possible to determine a higher level geography they were

included in the corresponding results (One case included in LA, county and England results

only.)

Confidence Limits:

Confidence limits provide an indication of the reliability of a result.

The 95% confidence intervals provide a range within which there is 95% chance of the true result lying.

Confidence intervals were calculated using Byar's Method as described in APHO Technical Briefing 3: Commonly used public health measures and their confidence intervals.
