**Selected angle:** `source`

## One-sentence thesis

The cited A/B receipts support a specific working claim: 30.90% of the ulcer area was significantly reduced in the therapy group compared with the control group; light delivered with power densities of 0.9 – 36 J/cm2 applied at 24 hours after injury reduced neurological deficits by 32%. The cited receipts are separate evidence streams; this memo maps a testable contrast, not one integrated analysis.


**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.

## Why this is surprising

Photobiomodulation's anti-inflammatory efficacy across at least seven autoimmune/inflammatory conditions (RA, SLE, MS, psoriasis, IBD, asthma) has been demonstrated at wavelengths spanning 633–904 nm, yet the field has never formally tested whether this convergence implicates a wavelength-agnostic mechanism distinct from the canonical cytochrome c oxidase absorption model. The simultaneous 70% ATP increase and 30% NF-κB reduction reported from the same 2025 cohort raises the untested question of whether these two pathways are causally linked or independently photoactivated.

Known / obvious (do not republish): PBM reduces wrinkles by ~31% in middle-aged women; PBM improves Parkinson's signs by ~90% intranasally; PBM improves scotopic thresholds in aging retina

Real tension: Facts 11,13,15 (810 nm, 10 J/cm² for RA) and Fact 16 (633 nm, 12 J/cm² for psoriasis) and Fact 12 (780 nm, 3 J/cm² for SLE) all report anti-inflammatory outcomes but at wavelengths with ≤40% overlap in CCO absorption spectra, challenging a single-mechanism explanation.

## Evidence Landscape

**Bounded research question:** Does the cited receipt bundle still support this bounded claim when population, endpoint, comparator, and time window are aligned?

## What this changes

Treat this as a focused working signal, not a broad topic claim. It moves review attention from a generic Top 5 list to the specific contrast, receipt bundle, and matched direct-receipt table by population, model, endpoint, comparator, and effect direction that could confirm or kill the thesis.

## Limitations

- This is an alpha memo, not a settled review, guideline, or broad consensus claim.
- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.
- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.
- Independent receipts fail to reproduce the claimed contrast.
- The effect depends on one protocol, subgroup, comparator, or extraction artifact.

## What would weaken this

- Independent receipts fail to reproduce the claimed contrast.
- The effect depends on one protocol, subgroup, comparator, or extraction artifact.

## Strongest counter-evidence

- _Within the currently bound receipt bundle, no A_core/B_context opposing fact was selected. Treat that as a bundle limitation, not a claim that the wider literature has no counter-evidence._

## Next extraction

- Extract independent A_core/B_context receipts that test the lead contrast directly.
- Audit whether each direct receipt remains comparable on population, endpoint, comparator, and measurement method.
