From open datasets, joined by identifier and shown only for properties Wikidata does not state on this entity — except where the dataset is the registry authority for the fact (ClinicalTrials.gov on trial registration data): there its value is shown instead, with Wikidata's noted beside it. Every row carries its dataset edition and licence.

high ≥ 0.90 · emerging ≥ 0.65 · low below — calibrated against hand-rated truth (single-source .44 · two-source .62 · production-typical .70), so a band is a measurement, not a promise. High is rare by design: it needs both a supported assertion and an evidence sentence. A confirmed or contradicted chip is a Wikidata cross-check; no chip means Wikidata has no value for that property — the ordinary case here, and it says nothing either way. A confirm-only note marks a property whose check can never disagree (Wikidata's border and capital data is not exhaustive), so silence there is a limit of the check, not of the claim.

Published, not hidden — scoring low is not a reason to withhold a sourced claim. A contradicted chip means Wikidata holds a different value; both are shown so you can judge.
