We gratefully acknowledge the relentless effort of the field officers involved in data collection and compilation.
We included neurological examination findings in our data compilation and added information given by other departments like gynaecology, internal medicine and otolaryngology.
For both groups, a third party, who had not taken part in the data compilation process, keyed the variables into the statistical data-base.
The overall frequency of breast cancer was significantly lower in this data compilation compared with our original series (21/72, 29% vs. 8/14, 57%, P = 0.043, chi square test).
The genetic associations identified in this data compilation included those with single KIR genes, profiles of combined KIR genes and / or HLA class I ligands, and full KIR genotypes.
The NHIRD was established in 1996 and became more comprehensive in terms of data compilation in 1997.
IFE designed and coordinated the study, participated in the immunoassays and their interpretation, participated in the clinical data compilation, participated in the statistical analysis and drafted the manuscript.
It is important to assess the quality of measurements taken in the field, data compilation and data analysis in order to generate error estimates and improve future measurements.
LLL assisted in the coordination, data compilation and sample processing.
