Quick Answer
Zinc Immune Meta-Analysis has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: Zinc deficiency has been associated with impaired immune responses, increased oxidative stress, compromised intestinal barrier function, and delayed wound healing-all of which are particularly relevant in the pathophysiology and management of IBD [,].

- 0210 11 12 13 14 Multiple mechanisms contribute to zinc deficiency in IBD patients, including reduced dietary intake due to food aversions and restrictive diets, malabsorption secondary to intestinal inflammation and mucosal damage, increased gastrointestinal losses through diarrhea and protein-losing enteropathy, and drug-nutrient interactions with medications such as sulfasalazine and corticosteroids [,]. [Muacevic Alexander (2026)]
- 03Between-study heterogeneity was evaluated using Cochran’s Q test (with p<0.10 considered evidence of significant heterogeneity) and quantified using the I² statistic, where values above 75% reflected high heterogeneity, 50-75% represented moderate heterogeneity, and values below 50% indicated low heterogeneity.

Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
