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

introductionWe performed a meta-analysis to compare the clinical and endoscopic recurrence of medical treatment and placebo treatment for preventing postoperative recurrence in Crohn's disease. MATERIALS AND

methodsTrials were located through Medline, Embase, the Cochrane Central Register of Controlled Trials, Ovid, Sciencedirect, and Ingenta electronic databases. From 124 articles screened, 14 were identified as randomized placebo-controlled trials and were included for data extraction. Main outcome measures were clinical recurrence, endoscopic recurrence, and severe endoscopic recurrence. The meta-analysis was performed with the fixed-effects model.

resultFourteen studies with 1,497 participants were analyzed. In the intention-to-treat analysis, medical treatment was associated with a significantly lower incidence of clinical recurrence (relative risk of 0.74, 95% confidence interval 0.64-0.87, P = 0.000], but there were no significant differences in endoscopic recurrence (0.94, 0.83-1.07, P = 0.353) and severe endoscopic recurrence (0.83, 0.60-1.16, P = 0.281) between the two groups. When using per-protocol analysis, the results is similar, medical treatment was associated with a significantly lower incidence of clinical recurrence (0.84, 0.72-0.97, P = 0.020), but there were no significant differences in endoscopic recurrence (0.94, 0.85-1.05, P = 0.268) or severe endoscopic recurrence (0.76, 0.55-1.04, P = 0.084) between the two groups of patients.

conclusionsMedical treatment has a sufficiently beneficial effect on decreasing the risk of clinical postoperative recurrence in patients with CD.
