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

purposeAgeing is associated with a decline in gastrointestinal (GI) functions, but data on GI symptoms in older adults remain limited. This study assessed the prevalence of GI symptoms, irritable bowel syndrome (IBS), and faecal short-chain fatty acids (SCFAs) in older adults, and associations between GI symptoms and faecal SCFAs, dietary intake, and BMI.

methods907 older adults (66-69 years, 50.7% females) from the community-based Hordaland Health Study 3 - Microbiota study were included. GI symptoms and IBS status were assessed by validated questionnaires (Gastrointestinal Symptom Rating Scale, Rome IV-criteria, IBS-Severity Scoring System), dietary intake by a 279-item food frequency questionnaire, and the concentration of SCFAs were measured from faecal samples.

results33.9% experienced at least one GI symptom, 16.4% reported IBS-like symptoms, and 5.0% had IBS according to Rome IV-criteria. Indigestion was the most common GI symptom (24.2%). Females had a higher total mean score of GI symptoms (p = 0.021), with higher frequencies of constipation (p = 0.006) and abdominal pain (p = 0.031), compared to males. Males had higher concentration of total faecal SCFAs (p = 0.004) and all major SCFAs compared to females. Total faecal SCFAs were negatively associated with constipation, independently of dietary fibre intake, total energy intake, sex and BMI (B =  - 0.006, 95% CI [- 0.009, - 0.004], p < 0.001). We observed a positive correlation between total faecal SCFA concentrations and diarrhoea (r = 0.072, p = 0.039) and looser stool consistency (r = 0.185, p < 0.001); however, these associations did not persist in the regression analyses. All GI symptoms positively correlated with increasing BMI.

conclusionGI symptoms are common in older adults, and IBS is at least as prevalent as observed in the general adult population. Improving dietary habits and preventing overweight and obesity may reduce the risk of GI symptoms and improve gut health in older adults.
