Introduction to the age-related diagnosis (ARD) index: an age at presentation related index for diagnostic use.
Development and, therefore, age is important in paediatrics. Diagnostically useful data from this journal has been related to age and organized to form an age-related diagnostic (ARD) index. The ARD index is designed for non-expert clinical and laboratory workers to use in the early phases of diagnosis and as an addition to existing diagnostic schemes. Entry to the index is from the age at clinical presentation. Each entry is a sequence starting with clinical and laboratory presentations, clinical course, laboratory key investigations and finally diagnosis with volume and page numbers of the original article, the primary source. Within age groups, entries are grouped by diagnoses with the commonest diagnosis first; this has the effect of roughly but not precisely grouping similar clinical and laboratory findings.
