Odds ratio between men and women aged 30–45 for Angina (history and/or Rose): 1.5 (0.5 to 4.1); p value 0.417**. Odds ratio between men and women aged 46–60 for Angina (history and/or Rose): 4.6 (2.1 to 9.9); p value 0.002**. Odds ratio between men and women aged 61–75 for Angina (history and/or Rose): 1.5 (0.6 to 3.6); p value 0.329**. Odds ratio between men and women aged 30–75 for angina (history and/or Rose): 2.28 (1.23 to 4.22); p value 0.015**. The prevalence of angina between general practices varied from 0–12.5% in men and 0–20.3% in women. There was little overlap between the practices that had the highest levels in men and women.
ICC—whole sample 0.016; ICC men—0.023; ICC women—0.018.
↵* 95% CIs for sample prevalences estimated using survey:proportion to adjust for possible clustering between practices.
↵† Using survey:logit to adjust for possible clustering between practices.
Standard error for age standardised rate (ASR) using the formula:
where Ni is the number in age group i in Goa census data, ri is the rate in age group i in the sample, and ni is the number in the age group i in the sample. The 95% CI is then ASR±1.96SE(ASR).
