Claim

The claim concerns additional analyses of individual academic scholars in China, using annual PM2.5 exposure whose study-period mean was 45.91; the reported work-hour, hospital-visit, and collaboration associations are not the primary publication-count outcome, and the full micro-level tracking data are not publicly available.

Main unresolved issue: 2 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:a7657e51-882e-84b0-8530-9395b2f67f06

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 article states that full micro-level tracking and longitudinal publication data are not publicly available. 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 Supported.

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 + 3.600000 (the counted weights) = 3.600000 → probability 0.9734

Under neighbouring settings of the same model: 0.9255 to 0.9908, a spread of 0.0653.

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.

Inferences

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.
