meta-analysis of proportion_- problem with showing the 95% CI for the I-squared statistic

[Martha Chipinduro]

I performed a meta-analysis of proportion using the metan command in Stata ver 17.0 and genertaed a forest plot. The forest plot shows I² reported with the p-value, however I need to report it with a 95% CI. Using the suggestion of just adding the option i2ci at the end of the code produces an error. The log file does not show the 95%CI for I².

***code begin***
metan discordant_pairs total-household_pairs, pr model(ivhet) transform(fturkey, iv) study(study) by(tbincidence_category) sortby(tbincidence_id) forestplot(astext(40) textsize(100) boxscale(50) spacing(1.2) leftjustify range(01) dp(2)) extraline(yes) hetinfo(isq h) i2ci
***end of code***

***begin of error***

option i2ci not allowed
r(198);

***end of error***
