## Incidence-rate data on fiber intake and coronary heart disease risk

### Description

The dataset reports the summarized dose-response results from incidence-rate data investigating the association between the long-term intake of dietary fiber and risk of coronary heart disease among women, first presented by Wolk et al. (1999)

### Format

A data frame with 5 observations on the following 8 variables:

 dose assigned dose levels. cases number of cases for each exposure level. n total number of subjects for each exposure level. adjrr adjusted incidence rate ratios for each exposure level. lb lower bound for the confidence limits of the adjusted incidence rate ratios. ub upper bound for the confidence limits of the adjusted incidence rate ratios. logrr natural logarithm of adjusted incidence rate ratios. se standard error for the logarithm of the adjusted incidence rate ratios.
