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

backgroundCommon gastrointestinal disease irritable bowel syndrome (IBS) is marked by symptoms like changed bowel habits, bloating, and stomach ache. A low-FODMAP combined gluten-free diet (LF-GFD) has been suggested as a possible therapy for IBS symptoms management.

objectiveThis study sought to investigate whether a LF-GFD would help patients with IBS.

methodsStrict inclusion and exclusion criteria from internet databases helped to identify clinical studies evaluating the intervention of LF-GFD in the treatment of IBS patients. Using measurements including the visual analog scale (VAS) for bloating and pain, the IBS symptom severity scale (IBS-SSS), and IBS quality of life (IBS-QoL), the main results evaluated were the efficacy of LF-GFD in reducing IBS symptoms. Furthermore assessed were the psychological impacts of LF-GFD utilizing the self- rating depression scale (SDS) and self- rating anxiety scale (SAS).

resultsA total of 437 patients (221 on LF-GFD diet and 216 on GFD) were involved in 4 randomized controlled trials and 4 cohort studies. The combined results indicated that LF-GFD reduced the VAS bloating ratings (RR = - 0.58, 95%CI - 0.92-0.23, P = 0.0010, I2 = 83%) and the VAS pain scores (RR = - 0.42, 95%CI - 0.66-0.19, P = 0.005, I2 = 58%). In addition, LF-GFD indicated a substantial enhancement in IBS-SSS scores (MD = - 1.42, 95%CI - 2.74-0.10, P = 0.03, I2 = 24%) and IBS-QoL ratings (MD = 3.75, 95%CI 0.98-6.53, P = 0.008, I2 = 33%). Moreover, the LF-GFD group showed a substantial drop in SDS (MD = - 2.56, 95%CI - 3.38-1.74, P < 0.00001, I2 = 65%) and SAS (MD = - 4.30, 95%CI - 6.53-2.24, P < 0.0001, I2 = 0%) scores compared to the GFD group.

conclusionLF-GFD therapy significantly enhances clinical symptoms and reduces anxiety and depression in individuals diagnosed with irritable bowel syndrome.
