There was criticism of the meta analysis that you quote
The criticism of the meta-analysis you are asking about is not something the evidence here can evaluate, because it contains no meta-analysis of placebo-controlled homeopathy trials and no discussion of sensitivity to study selection or bias.
The only placebo-controlled trial in this retrieval is a 1997 study on muscle soreness [6]. It found the homeopathic group had mean soreness of 2.38, the placebo group 2.21: no meaningful difference. A combined analysis of prior data also showed no difference [6]. That matches your hypothesis that the overall picture is null.
But this retrieval is too thin to test your hypothesis properly. It contains no individual patient data analysis, no exploration of heterogeneity by study quality, and no sensitivity analysis comparing different inclusion criteria. The three other reviews here either found no conclusive evidence [1] or relied on uncontrolled case reports and in vitro experiments [2, 3, 4, 5]. None of them probe whether meta-analytic conclusions are fragile to study selection.
| Evidence type | What it tests | What it found |
|---|---|---|
| Placebo-controlled RCT [6] | Homeopathy vs placebo for muscle soreness | No difference (2.38 vs 2.21 soreness) |
| Systematic review (depression) [1] | CAM monotherapies vs placebo | No conclusive efficacy |
| In vitro gene expression studies [3, 5] | Homeopathic dilutions on cell lines | Some gene changes, no clinical meaning |
| Case report (personality disorder) [4] | Single-dose homeopathy | Recovery described, no control |
My call: the criticism of meta-analytic sensitivity you describe is a legitimate methodological concern, but the evidence here provides no way to assess it. The best-controlled study returns a null result. Confidence: low — the available evidence is too sparse and too narrow to evaluate the hypothesis that meta-analytic conclusions are sensitive to study selection.

The evidence base of complementary and alternative therapies in depression
This review of 19 studies found no conclusive evidence of efficacy for any CAM monotherapy in depressive disorders; highest-level evidence was equivocal, inconclusive, or negative.

Experimental Evidence Supports New Perspectives in Homeopathy
The paper argues that recent experimental evidence of nanoparticles in homeopathic remedies and hormetic gene-expression effects supports redefining homeopathy as nano-dose pharmacology, bridging conventional and homeopathic medicine.

Arnica montana effects on gene expression in a human macrophage cell line. Evaluation by quantitative Real-Time PCR
This in vitro study investigates how Arnica montana dilutions modulate gene expression in THP-1 human macrophages (normal and IL-4-polarized wound-healing phenotypes), revealing dose- and time-dependent, non-linear changes in inflammatory and tissue-remodeling genes that hint at…

Homoeopathy for delayed onset muscle soreness: a randomised double blind placebo controlled trial.
This randomized, double-blind, placebo-controlled trial evaluated a homeopathic remedy for delayed onset muscle soreness (DOMS) induced by bench stepping in healthy volunteers, finding no evidence of benefit over placebo, and a combined meta-analysis with prior data also showed …
