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

BACKGROUND/

objectivesMalnutrition and diabetes mellitus (DM) have been linked to gut microbial perturbations, yet data are scarce for the aging population, especially in a nursing-home setting. As this group is generally at risk for malnutrition, we aimed to investigate the link between DM and gut microbial patterns in interaction with nutritional risk status in nursing-home residents.

methodsStool samples were collected from 173 nursing-home residents (77.5% female, mean age 86 years) and were analyzed via 16S rRNA sequencing. Furthermore, the Geriatric Nutritional Risk Index (GNRI) was assessed and data on comorbidity status, anthropometric measurements, and medication were acquired.

resultsFifty-one residents had DM (mean HbA1c 6%). There were no DM-related differences in alpha diversity (observed richness:

conclusionsWe report malnutrition-related differences in beta diversity and diabetes-related microbial taxa differences in nursing-home residents. DM status did not influence the relationship between the GNRI and gut microbiota in this population.
