1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND AND

aimsWe conducted a systematic review and meta-analysis evaluating the relapse rate after therapeutic de-escalation in inflammatory bowel disease [IBD] patients who achieved deep remission [DR].

methodsWe searched MEDLINE, EMBASE, and major gastroenterology conferences up to July 2019 for studies reporting relapse in adult patients with DR who subsequently underwent therapeutic de-escalation. Eligible studies defined DR as at least a combination of clinical remission and mucosal healing/endoscopic remission. The primary outcome was cumulative 1-year and 2-year relapse rates after therapeutic de-escalation. Secondary outcomes were relapse rates in ulcerative colitis [UC] and Crohn's disease [CD], relapse after anti-tumour necrosis factor-α [anti-TNFα] de-escalation, and the rate of disease response recapture following re-escalation.

resultsThirteen studies encompassing 837 patients were identified. The cumulative relapse rate after therapeutic de-escalation was 28.7% within 1 year [12 studies], and 38.4% within 2 years [eight studies]. Relapse rates within 1 year and 2 years were comparable between UC [five studies; 25.4% and 37.4%] and CD [seven studies; 34.1% and 39.9%]. Ten studies reported de-escalation of anti-TNFα, of which 29.8% patients relapsed within 1 year and 41.4% within 2 years. Response recapture following re-escalation [eight studies] was 75.4%.

conclusionsDespite achieving deep remission, therapeutic de-escalation in this patient population is associated with significant relapse risk within 1 year and 2 years. This risk is more pronounced in patients requiring anti-TNFα for management, likely because of more severe disease. Similar rates of relapse were reported among UC and CD within these time periods. These findings suggest that combined clinical and endoscopic remission should not be an impetus to consider therapeutic de-escalation.
