Missing was generally low for non-sex related scales (< 2%, except for 4.4% for intravesical treatment at first visits), sexual function (highest with 10.4% at first visit), and male sexual problem (highest with 9.0% at first visit) ( Table 2) . However, missing rates were as high as around 50% for sexual intimacy, risk of contaminating a partner scale, and sexual enjoyment scale, which are instructed to be answered by those who have been sexually active during the past 4 weeks, and female sexual problem scale. When limited to those who reported at least a little sexual activity (item 48) at the each time point, response rate was around 75% (Table 2 ).
