Abstract

Sixty-four patients with proven ulcerative colitis who had been maintained on sulphasalazine as their sole form of treatment for a minimum period of one year were entered into a controlled trial of sulphasalazine versus dummy tablets for a period of six months. All the patients admitted were not only symptom-free but also showed no evidence of inflammation on sigmoidoscopy and rectal biopsy. A patient was judged to have relapsed when there was a recurrence of colitic symptoms accompanied by sigmoidoscopic and histological evidence of inflammation. The patients who received dummy tablets had more than four times the relapse rate of those receiving sulphasalazine. The results were similar in patients who had been on maintenance treatment with sulphasalazine for less than three years before entry into the trial and in those who had been on this treatment for more than three years. It is concluded that maintenance treatment of ulcerative colitis with sulphasalazine should be continued indefinitely unless contraindicated by side effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
