Claim: Cochrane's RoB 2 has five bias domains. COI/funding conspicuously absent.
BLUF: Factually confirmed with nuance on editorial characterization. RoB 2
has exactly five bias domains and COI/funding is absent. The "conspicuous"
characterization is defensible given published debate, but one-sided -- the tool
developers have articulated deliberate reasons for the design choice.
Probability: Very likely (80-95%) | Confidence: High
