Here is a further example inspired by Harrel (2001, Figure 20.4): To use different line widths specify the lwidth() suboption within ciopts(): Line widths are (logarithmically) increased across the confidence intervals. Here is an example with 99.9%, 99%, and 95% confidence intervals: To specify a different level or to include multiple confidence intervals, use the levels() option. The default for coefplot is to draw 95% confidence intervals (or as set by set level).

coefplot domestic foreign, drop(_cons) xline(0) ciopts(recast(rcap)) regress price mpg trunk length turn if foreign=1 regress price mpg trunk length turn if foreign=0 Use ciopts(recast()) to change the plot type. By default coefplot draws confidence intervals as spikes.
