Assessment

Why?

Strongest counted support: The primary abstract reports restoration of lymphatic density and tissue homeostasis after Vegfc overexpression or Il33 silencing in aged hearts. weight 2.000000 evidence

Strongest counted contradiction: In the aged-heart model, VEGF-C restoration reduced inflammation but did not improve heart function after eight weeks. weight 0.459000 evidence

Suppressed as dependent: The passage directly reports Vegfc overexpression or Il33 silencing restoring lymphatic density and tissue homeostasis in aged hearts, but not the potential-target conclusion.

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 Leans supported.

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.
