What the study showed

The document is a study protocol, not a results report. It outlines the plan to assess 15 g/day low-methoxyl pectin versus placebo over six weeks in 30 adults with MASLD. Planned outcomes include inflammatory markers, gut microbiome composition, liver stiffness (FibroScan®), and hepatic MRI characteristics.

How it was done

Single-centre, double-blind, randomised (1:1), placebo-controlled dietary intervention at Nottingham University Hospitals NHS Trust. Fasting blood samples, stool samples, and FibroScan® assessments will be collected at baseline and post-intervention; 22 participants will undergo an MRI sub-study.

Risk of bias

No efficacy data exist at this point — this is a protocol only. The sample size (n=30) is very small, limiting statistical power and generalisability. Six weeks may be insufficient to detect clinically meaningful changes in hepatic steatosis.

Interpretation limit

What this study does NOT prove

This protocol does not demonstrate that pectin improves any outcome in MASLD — trial data have not yet been collected or analysed.

In clinical practice

No clinical practice change is warranted from this document. Reading should be restricted to methodological design.

Limitations

No efficacy data exist at this point — this is a protocol only. The sample size (n=30) is very small, limiting statistical power and generalisability. Six weeks may be insufficient to detect clinically meaningful changes in hepatic steatosis.
