The standardised proportion ratio (SPR) by race was 1.70 (95% CI 1.45 1.99); that is, the proportion of black miners with silicosis was 70% higher than that for white miners over the entire period, but this varied over the study period.
11 25 During the 2009 pandemic in New Zealand, the age-standardised proportion of confirmed cases in 5-year-olds to 19-year-olds fell during the winter holiday and increased when schools reopened 19; a slight increase in influenza-like illness (ILI) consultation rates when schools reopened was confined to 5-year-olds to 14-year-olds.
18 The index is a standardised sum of the proportion of all unemployed men, persons in households with one or more persons per room, proportion of residents in households with no car and proportion of residents in households with head of household in Social Class IV or V (Registrar General's classification).
An alternative approach to monitoring and evaluating food advertising is by using children audience composition data as a standardised method to capture significant proportions of children exposed to marketing campaigns (1).
To assess the prevalence of LBC uptake, we used the first cervical cytology test for each woman who had cytology in each quarter, and calculated the age-standardised proportions of these tests for which adjunctive LBC was used, using the Australian 2001 standard population.
19 We presented standardised differences as a summary measure of differences between groups; we calculated a standardised difference as the difference between the sample means (or proportions), divided by the pooled standard deviation.
However where such sub-groups were the result of post hoc analysis not consistent with delivery of the intervention a standardised figure across all groups was calculated using Australian population data (eg proportion male/female in target age group).
Here we have shown that a standardised approach to analysing PD-related microarray data can account for a considerable proportion of the discordance.
Given a standardised volume, it was also conjectured that this concentration decrease would be linear, with a relative proportion of the protein being lost at each step.
No data were available in terms of proportion of patients with major depressive disorder at follow-up, as established with help of a standardised diagnostic interview.
