On the use of regression analysis for the estimation of human biological age.

The present investigation compares three linear regression procedures for the definition of human biological age (bioage). As a model system for bioage definition is used the variations with age of blood hemoglobin (B-hemoglobin) in males in the age range 50-95 years. The bioage measures compared are: 1: P-bioage; defined from regression of chronological age on B-hemoglobin results.

On the use of patient data for the definition of reference intervals in clinical chemistry.

To improve the definition of reference intervals using patient data in clinical chemistry we studied the use of single results as a selection criterion (i.e. those results judged by the clinician not to require confirmation or which are considered unimportant for clinical screening purposes).

Prognostic significance of birth of large infant for subsequent development of maternal non-insulin-dependent diabetes mellitus: a prospective study over 20-27 years.

In a prospective study, 270 women who gave birth to infants weighing greater than or equal to 4500 g (large baby, LB) underwent an oral glucose tolerance test (OGTT) within the first week of the puerperium. Of these women, 179 (66.3%) were retested 3-10 yr later, and 236 (87.

Spinal proteins in patients with acoustic neuromas.

The values of total spinal protein in cerebrospinal fluid (CSF), used as normal material, from 98 persons are presented. These values showed that the previously used reference limits (0.20-0.
