The Appeal Gap: Initial Approval vs. Board Outcomes for the Top 10 Disabilities
The ten most common VA service-connected disabilities cover most of the 6,338,253 veterans currently receiving compensation. This report lines up how often each is approved on an INITIAL claim (GAO analysis of VBA data) against how often the SAME conditions are granted once a denial reaches the Board of Veterans' Appeals, a very different, much harder population.
Two different populations, read carefully: the initial-approval column describes every veteran who filed a first claim for that condition. The Board column describes only veterans who were DENIED and chose to appeal all the way to the Board, a smaller, self-selected, harder-fought group. A large gap does not mean "the Board reverses most claims", it means the easy grants never reach the Board at all; what's left to appeal is disproportionately the hard cases.
Initial claim vs. Board appeal, by condition
Initial approval rate is GAO's FY2010-2020 analysis of VBA's own data. Board grant rate is granted of decided (granted+denied) issues in our full published-decision corpus. The gap column is initial-approval minus Board grant rate, a positive number means the condition grants MORE often on an initial claim than on Board appeal:

Methodology
Initial-approval percentages and veteran counts are GAO-23-106097 and the VA Annual Benefits Report FY2025, external federal sources, not derived from our corpus; they are curated and hand-updated when a newer report publishes. Board figures are issue-level aggregates over published Board of Veterans' Appeals decisions for the same 10 diagnostic codes: grant rate is granted divided by granted-plus-denied; the dispositive-element breakdown uses the same Caluza-element methodology (missing diagnosis, missing in-service event, or missing nexus) as the Missing Nexus report, requiring at least 20 classified denials per condition. Figures refresh weekly as new decisions publish.
