Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Hp Stool Antigen (HpSA)+FIT | HpSA for detection of upper gastrointestinal tract diseases and upper endoscopy for H. pylori carriers; HPSA combined with FIT~FIT(Eiken OC-Sensor) One-day sampling: One-day sampling~FIT(Eiken OC-Sensor) Two-year interval: Screening with two-year interval~HpSA (Firstep Helicobacter pylori Antigen Rapid Test): HpSA for detection of upper gastrointestinal diseases; screen and treat for H. pylori infection. Upper endoscopy for H. pylori carriers. HPSA+FIT compared with FIT alone. | 49 | 31,497 | OG000 | ClinicalTrials.gov |
| Group 2 | FIT Only | HpSA + FIT compared with FIT alone~FIT(Eiken OC-Sensor) One-day sampling: One-day sampling~FIT(Eiken OC-Sensor) Two-year interval: Screening with two-year interval~FIT only: HPSA+FIT compared with FIT alone. | 59 | 31,777 | OG001 | ClinicalTrials.gov |
