Start is estimated for Feb 2022; primary completion for Jan 2024, 22 months later.
Of 274 non-industry observational studies under Stomach Neoplasms, half reached primary completion within 59 months of starting (the median), counting those still running; a quarter within 30 and three quarters within 171. This study's planned 22 months is below that.
Counting every sponsor, half of 305 studies reached it within 56 months; a quarter within 30 and three quarters within 120.
