Endoscopy Assessment at 1-Year Identifies Long-Term Responders to Thiopurines Maintenance Therapy in Patients With Crohn's Disease.
Article in Medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
When treating Crohn disease (CD) with thiopurines, achievement of an objective response is essential. However, the minimal degree of mucosal improvement required to alter disease outcomes of CD is unknown.To determine the endoscopic responses of thiopurine monotherapy and to determine the minimal degree of mucosal improvement required to alter disease outcomes of CD.One hundred thirty CD patients who had evaluable ileocolonoscopy with evident of mucosal ulceration at baseline were included. The endpoints were endoscopic responses at the 2 follow-up endoscopies performed at 12 months (M12) and 36 month (M36) from the initiation of thiopurines.At M12, mucosal healing (MH) and a positive endoscopic response (PR) were documented in 38% and 46% of patients, respectively. At the second follow-up, merely a further 14% (13/93) of patients on monotherapy had a PR and a total of 46% (43/93) presented with MH. In a Cox regression model, both a PR (P < 0.02) and MH (P < 0.001) at M12 were associated with response at M36 in patients continuing thiopurine treatment. MH at M12 was associated with long-term disease outcomes of CD at M36, with an area under the Receiver Operator Characteristic curve of 0.54 for predicting clinical remission, 0.69 for hsCRP normalization, 0.69 for MH, and 0.74 for PR, respectively. A PR at M12, defined as a decrease in endoscopic activity score by ≥2 points from baseline, yielded similar results.Endoscopy at M12 can help to identify responders to thiopurine monotherapy in active CD. A PR could represent the minimal clinically important improvement in endoscopic disease activity.
