Evidence in granted and denied major depressive disorder decisions
For each kind of supporting evidence: how often the Board granted the major depressive disorder issue on the merits when the decision mentioned it, compared with decisions that did not. These are associations, not causes, and evidence is recorded per decision, not per issue.
| In the record | Decisions | Granted when present | When absent | Difference |
|---|---|---|---|---|
| Positive nexus opinion | 154 | 97.0% | 71.1% | +25.9 pts |
| Favorable VA exam | 113 | 96.1% | 79.1% | +16.9 pts |
| Combat service | 64 | 92.5% | 85.4% | +7.1 pts |
| Treating physician opinion | 47 | 92.5% | 85.9% | +6.6 pts |
| Private medical opinion | 125 | 90.0% | 84.6% | +5.4 pts |
| Lay statement | 262 | 86.2% | 95.5% | −9.3 pts |
- The Board applied the benefit-of-the-doubt rule (38 CFR 3.102) in 71.4% of the decisions that granted major depressive disorder.
- The Board found the veteran's statements credible in 47.6% of grants and 17.9% of denials.
Negative evidence in the record
An unfavorable exam or a negative nexus opinion often sits in the same record as favorable evidence, and the Board weighs them against each other. So these rows show how often major depressive disorder was still granted when the record contained the negative item, not that the item helped.
| In the record | Decisions | Granted when present | When absent | Difference |
|---|---|---|---|---|
| Negative nexus opinion | 141 | 81.2% | 92.2% | −11.1 pts |
| Unfavorable VA exam | 206 | 82.8% | 97.0% | −14.2 pts |

How these numbers are calculated
- Counts decisions in which the Board decided a major depressive disorder issue claimed as secondary to PTSD, by the outcome of that issue.
- The primary disability is read from the decision text ("secondary to …") and grouped by name, so spellings such as "PTSD" and "posttraumatic stress disorder" count together.
- Secondary claims also include aggravation of a non-service-connected condition by a service-connected one (38 CFR 3.310(b)).
- The data comes from CaseScribe's AI extraction of public BVA decisions (2017–2026) and can contain errors. It is updated automatically as new decisions are added.
