Claim

In a cluster-randomized trial of 400 permanent-supportive-housing residents, a brief smoke-free-home intervention did not significantly increase adoption maintained for at least 90 days at six months, although it increased one-day smoke-free-home adoption and seven-day point-prevalence abstinence.

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.

Why?

Strongest counted support: The intervention lacked a significant 90-day sustained adoption effect but increased one-day smoke-free-home adoption and seven-day abstinence. weight 1.800000 evidence

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + 1.800000 (the counted weights) = 1.800000 → probability 0.8581

Under neighbouring settings of the same model: 0.7790 to 0.9121, a spread of 0.1331.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

None.

Qualifications

The packet supports the 400-resident sample, null 90-day adoption result, and increased one-day adoption, but omits the seven-day abstinence result.

The packet does not establish every clause in the claim.
The counted passage reports 400 residents, six-month sustained adoption, and one-day adoption, but omits cluster randomization and the seven-day abstinence outcome.

None.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
