For diabetes appeals, how often the Board granted the issue when the record held each kind of evidence, and how often when it did not. Measured from the decisions themselves; every number carries its fraction.

"Granted" = share of issues decided on the merits (granted + denied); remands and dismissals are excluded from that fraction and shown separately. Fractions are the raw counts.
Association, not cause. A positive nexus opinion appears in the records of granted appeals far more often than in denied ones. That does not mean any letter wins; it means the Board grants when the evidence supports the claim, and a nexus opinion is how that support usually reaches the file.
Appeals are not claims. Every decision here is an appealed denial. Grant rates at the Board say nothing about the share of initial claims VA grants.
Findings are outcomes in disguise. Rows under "how the Board read the record" — credibility, benefit of the doubt, an inadequate exam — describe how the judge decided, not evidence to gather. They are shown because they say which arguments the Board actually reaches for.
Detection is by text pattern. Each evidence type is found by reading the decision for finding-shaped language with negation handling; precision was read on samples before publication and is stated per feature in the method notes below. Expect a few percent of misclassified rows, not zero.
VetAid's free analyzer reads your decision letter and records, then ranks the evidence gaps by exactly these numbers — for your conditions, not the average.
