We surmounted formidable technical, ethical, administrative and legal challenges to link census, CHI, hospital and mortality data for analysis of the relationship between ethnicity and disease.
The only mortality data available for analysis were numbers found dead in the hives and on the linen sheets in front of the hives.
Mortality data for the analysis were supplied via the Warwickshire Public Health Intelligence Team and was sourced from the Public Health Mortality Files, Office for National Statistics.
PKS was responsible for the Health and Demographic Surveillance System, icddr,b, verification of mortality data, contributed in analysis and writing up.
Once the original time series is decomposed into trend and non-trend IMFs, calculation of the excess mortality or other data analysis procedures (e.g., a subsequent regression analysis) can be performed using the resulting IMFs as the input.
To ensure completeness of data sets, the cohort and due to the availability of reference mortality data we restricted analysis to fire fighters who were active on January 1, 1950 or were employed before the end of follow up on June, 30, 2000.
Lethal concentrations of cypermethrin at which 50% mortality of the fish occurred (LC50) and its 95% confidence limits were estimated for 96 h from the mortality data using EPA-Probit analysis version 1.5 statistical software based on the probit analysis method of Finney (1971).
As an alternative to the standard methods of survival analysis, mortality data can be analysed with generalised linear models (GLM).
World Health Organization (WHO) mortality data were extracted for analysis.
No mortality data were available for analysis as mortality was reported as aggregated data.
