In order to take into account the large variation in sample sizes, weighted percentages were calculated by weighting each reported rate with the size of the study group.
We analysed weighted percentages with consideration of the complex survey sample design and unequal weights.
Values are weighted percentages or means derived using the HRS and ELSA respondent population weights to adjust for the complex sampling design of each survey.
Sample totals provided along with weighted percentages.
Further results are presented as weighted percentages.
We use weighted percentages and calculate unadjusted odds ratios using logistic regression.
Figure 2 shows the data on symptom distributions (using a composite ranking of frequency and severity) reported as weighted percentages by age groups.
Data are weighted percentages (95% CIs).
