Sustained wood moisture content above 25 percent is the controlling condition for fungal decay initiation in above-ground timber.

Under review — the register is reading the literature and will publish a conclusion once directional evidence has been indexed.

In plain terms

20 studies are indexed, but only 1 has been classified for or against — too few to state a consensus, so no share is calculated yet.

This sentence is generated from the same numbers shown below — consensus share, confidence band and the number of indexed studies. Open any section to see exactly how it was reached.

Where the literature disagreesNo direct contradictions in the indexed pool

No direct contradictions in the indexed pool. That is not the same as agreement — it can also mean too few directional studies have been published to disagree yet.

Measuring wood fungal decay by ultrasonic methods

Xia Hua · doi:10.31274/rtd-180813-8420

The title indicates ultrasonic measurement of fungal decay but gives no moisture threshold or initiation condition.

Neutral

Grade D · 0 citations

Not peer-reviewed

Moisture in modified wood and its relevance for fungal decay

EE Thybring, M Kymäläinen, L Rautkari · 2018 · iForest - Biogeosciences and Forestry · doi:10.3832/ifor2406-011

The review identifies moisture as essential for decay but does not establish a sustained 25 percent threshold for above-ground timber.

Neutral

Grade B · 41 citations

Peer-reviewed

Decay of Wood and Wood-Based Products Above Ground in Buildings

CG Carll, TL Highley · 1999 · Journal of Testing and Evaluation · doi:10.1520/jte12054j

The overview discusses optimum moisture, temperature, and inoculation but does not establish sustained moisture above 25 percent as controlling.

Neutral

Grade B · 71 citations

Peer-reviewed

Stance classification is automated and reviewed against each record's own abstract; it is a reading of the literature, not a measurement. The Evidence Score is a rule-based function of indexed metadata under method WI-EV v1.0.0 and does not constitute proof of the statement.
