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

backgroundAccumulating evidence suggests that additional dietary fiber supplements may significantly improve glycolipid metabolism and pregnancy outcomes in individuals with gestational diabetes mellitus (GDM). However, the therapeutic effects of xylose oligosaccharides and inulin (XOS inulin) in pregnant women have not been investigated. Moreover, the underlying mechanism behind the therapeutic effects of this type of dietary fiber is not clear. Our study aims to assess the effects of daily XOS inulin supplementation on glycolipid metabolism and elucidate the therapeutic mechanism through gut microbiota analysis.

methodsThis study is an 8-week, parallel-design, open-label, three-arm, single-center randomized controlled trial. Eligible participants were pregnant women between 24 and 28 weeks of gestation, and they were diagnosed with GDM through an oral glucose tolerance test (OGTT). The participants in the three groups will receive nutrition education alone, nutrition education plus XOS inulin (XOS 2 g and inulin 10 g) 12 g/day, or nutrition education plus XOS inulin 24 g/day. Measurements will be taken at baseline, week 4, and week 8. The primary outcome will be the change in glycosylated serum protein (GSP), and the key secondary outcomes include changes in fasting glucose, fasting insulin (FINS), 2-h postprandial plasma glucose (2 h-PPG), HbA1c, total cholesterol (TC), triglycerides (TG), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), and changes in the gut microbiota. DISCUSSION: This study will evaluate the therapeutic effects of XOS inulin supplementation on glycemic control, lipid metabolism, gastrointestinal function, and perinatal outcomes in GDM patients and their offspring. It also provides insight into the potential role of the gut microbiome as a target for enhancing the therapeutic efficacy of emerging treatments for GDM. All participants will receive comprehensive GDM nutrition education, promoting sustainable dietary modifications that optimize maternal metabolic health and fetal outcomes.
