Statistical methods / analysis
Outcome measures of SF, Hb, serum hepcidin, hsCRP, ESR and scoring of FSS and GSRS will be analysed using mixed ANOVA with repeated measures to detect any significant changes between groups over time. Pairwise comparisons with t-tests will be performed where significance is observed. The significance level is set at p<0.05.

Improvements in ID will be reported as response rates. The odds ratio of responding to treatment in the intervention group will be compared to the responding rate of the control group with the significance computed using Fisher’s Exact Probability Test.

The 16S rRNA sequences of extracted faecal DNA will be analysed with QIIME2
(Quantitative Insights into Microbial Ecology software) pipeline.
