Summary

This study compared two bowel-cleansing medicines (picosulfate sodium/magnesium citrate vs. polyethylene glycol) in 440 adults in Taiwan. The goal was to see which one cleans the colon better before a colonoscopy and which is safer and easier to take. Results help doctors choose the best prep for their patients.
