Number of participants that the trial has enrolled 879
Results 
In a nationwide study of patients with UC in Japan, we found that the level of FCP and FIT could each identify patients with endoscopic markers of disease severity.The combination of FCP and FIT results can identify patients in remission who are at risk for disease recurrence.

Baseline Characteristics 
To date, most studies on the usefulness of fecal biomarkers have been conducted with relatively small numbers of patients. There have been only a few large multicenter cohort studies on the efficacy of fecal biomarkers for clinical recurrence in patients with UC. Furthermore, it remains unclear whether FCP or FIT levels can reflect the extension of inflammation. Therefore, this nationwide prospective study aims to compare FCP and FIT on the usefulness of assessing endoscopic severity in UC and predicting short- and middle-term prognosis in patients in clinical remission.
Participant flow 
A total of 879 patients with UC were enrolled in this study from March 2015 to March 2017. These patients had been recruited from 16 institutions and were randomly enrolled. This study consisted of two cohorts.
Adverse events 
None
Outcome measures 
The primary endpoint in Cohort 1 was to evaluate the correlation between FCP/FIT and endoscopic severity. The primary endpoint in Cohort 2 was to assess the association between FCP or FIT level at baseline and clinical recurrence 
for 12 months in patients with UC in clinical remission.
