Assessment

Why?

Strongest counted support: The lowest-income tercile had significantly lower success rates, with the lowest-versus-highest comparison p < 0.0001 and OR 1.13 [1.10–1.16]. weight 1.800000 evidence

Suppressed as dependent: The passage directly reports lower success in low-income ZIP-code terciles and the stated p-value and odds ratio comparison.

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.

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.
