R0002/2026-03-13/C004 — ACH Matrix¶
Matrix¶
| H1: All elements accurate | H2: Mulrow is background only | H3: Characterization exaggerated | |
|---|---|---|---|
| SRC01-E01: PRISMA traces origins to Mulrow | ++ | -- | N/A |
| SRC02-E01: Zero of 50 reviews met all criteria | ++ | N/A | -- |
| SRC03-E01: James Lind confirms foundational role | ++ | - | - |
Legend:
- ++ Strongly supports
- + Supports
- -- Strongly contradicts
- - Contradicts
- N/A Not applicable to this hypothesis
Diagnosticity Analysis¶
Most Diagnostic Evidence¶
| Evidence ID | Why Diagnostic |
|---|---|
| SRC01-E01 | Strongly supports H1, strongly contradicts H2 — the PRISMA developers themselves credit Mulrow, eliminating the "indirect cause" framing |
| SRC02-E01 | Strongly supports H1, strongly contradicts H3 — the quantitative data shows the claim is an understatement, not an exaggeration |
Least Diagnostic Evidence¶
| Evidence ID | Why Non-Diagnostic |
|---|---|
| SRC03-E01 | Supports H1 and contradicts H2/H3, but as a secondary source it merely corroborates what the primary sources already establish independently |
Outcome¶
Hypothesis supported: H1 — All elements of the claim are accurate. Mulrow directly motivated PRISMA. The characterization is conservative.
Hypotheses eliminated: H2 — PRISMA developers explicitly credit Mulrow. H3 — The claim is an understatement, not an exaggeration.
Hypotheses inconclusive: None.
