Article in Journal of Crohn's & colitis, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. It is linked to trial NCT06312683 (Rifaximin for the Secondary Prevention of Recurrent Pouchitis), which is not on this map. Cited by 26 papers, 1 of them a synthesis that pooled it.

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.

Abstract

Objective: To examine whether patients with a mature normal pouch [> 1 year post ileostomy closure] have microbial stool characteristics that can predict pouch inflammation. Design: Patients undergoing pouch surgery were recruited prospectively. Microbiota analysis of faecal samples was by 16S rRNA gene pyrosequencing. All patients had a normal pouch at baseline [T1]. Those without pouchitis during the first year of follow-up [T2] comprised the 'Normal Pouch-sustained' group and those who had experienced an episode of pouchitis comprised the 'Pre-Pouchitis' group. Results: Twenty patients were recruited (age 53.6±13.1 years, pouch age [time from ileostomy closure] 8.1±5.1 years). Seven patients developed pouchitis during follow-up [within 265±93.6 days] and they were assigned to the Pre-Pouchitis group at T1: they had a decreased microbial diversity at T1 compared with the Normal Pouch-sustained patients [n = 13]. The Shannon diversity index for the Pre-Pouchitis patients was 3.4 vs 4.23 for the Normal Pouch-sustained patients [p = 0.011]. There were no substantial group differences in high taxonomic levels [order or above]. The genus Ruminococcus was significantly decreased in the Pre-Pouchitis patients' samples compared with those of the Normal Pouch-sustained patients (0.19% vs 0.78%, respectively, false discovery rate [FDR] = 0.05). The linear discriminant analysis with effect size estimation algorithm revealed that Lachnospira and Coprococcus genera were also decreased among Pre-Pouchitis patients compared with Normal Pouch-sustained patients [0.6% vs 1.95% and 2.1% vs 4%, respectively]. Conclusions: Patients with a normal mature pouch may be predisposed to acute pouchitis when faecal microbial diversity and certain microbial groups are decreased. These findings may aid in risk stratification of those patients.
