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

backgroundRegarding the controversial role of Blastocystis in inflammatory bowel diseases (IBD) patients, it seems that this protozoan may lead to an overgrowth of some non-beneficial bacteria. The current study aimed to investigate the co-existence of Blastocystis and Clostridioides difficile in IBD patients.

methodsStool samples of 102 IBD patients were collected and cultivated for C. difficile and Blastocystis. DNA extraction was performed on positive samples and C. difficile and Blastocystis were toxinotyped and subtyped, respectively. Fisher's exact test and logistic regression were employed to calculate the correlation between the existence of Blastocystis and its subtypes (ST) with C. difficile and its type of toxins. Also, the co-existence of Blastocystis and C. difficile with the frequency of defecations was evaluated.

resultsBlastocystis and C. difficile were observed in 17 (16.7%) and 26 (25.5%) of stool samples, respectively. From 26 C. difficilepositive isolates, 24 (92.3%) and 2 (7.7%) were tcdA+/B+ and tcdA+/B-, respectively. Also, 10 (58.8%) and 7 (41.2%) were Blastocystis ST1 and ST3, respectively. Statistically significant correlations between co-existence of Blastocystis and C. difficile and co-existence of these microorganisms and frequency of defecation (P < .035) were seen. There was no statistically significant correlation between subtypes of Blastocystis and colonization of C. difficile or its toxinotypes.

conclusionThe co-existence of Blastocystis and C. difficile in IBD patients was observed in the current study. Moreover, it can be proposed that these microorganisms may have synergistic effects on their colonization in the gastrointestinal tract.
