**Selected angle:** `source`

## One-sentence thesis

Structured evidence map for Exercise difference training control resistance: the cited literature reports 5 distinct A_core findings across 5 independent sources. These are presented as a synthesis spanning populations and endpoints, not a single unified claim; each finding and its source is listed below.


**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.

## Why this is surprising

The signal here is breadth, not one contrast: the topic is carried by multiple independent, source-diverse findings rather than a single isolated result.

## Evidence Landscape

**Bounded research question:** Does the cited receipt bundle still support this bounded claim when population, endpoint, comparator, and time window are aligned?

## Evidence receipts

- `fact_id=157543` (`A_core`) — preoperative exercise training was associated with a lower incidence of PPCs (23 studies, 1,864 patients; relative risk, 0.52; 95% confidence interval [CI], 0.41 to 0.66) doi=10.1513/annalsats.202002-183oc
- `fact_id=153892` (`A_core`) — relative risk (RR) 0.83, 95% confidence interval (CI) 0.26 to 2.68; 2 trials, 131 participants doi=10.1002/14651858.cd010876.pub3
- `fact_id=138567` (`A_core`) — no effect was observed for postoperative complications (Odds Ratio 0.81, 95% CI 0.55-1.18; p = 0.27) doi=10.3389/fsurg.2021.628848
- `fact_id=148171` (`A_core`) — ET (HR = 0.75, 95% CrI = 0.56⁻0.99) and PE (HR = 0.68) doi=10.3390/jcm7120514
- `fact_id=157782` (`A_core`) — Diabetes incidence was only reported in two studies, with reductions of 58% and 56% versus control groups. doi=10.1186/1479-5868-11-2

## What this changes

Treat this as a focused working signal, not a broad topic claim. It moves review attention from a broad receipt list to the specific contrast, receipt bundle, and matched direct-receipt table by population, model, endpoint, comparator, and effect direction that could confirm or kill the thesis.

## Limitations

- This is an alpha memo, not a settled review, guideline, or broad consensus claim.
- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.
- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.
- The thesis stays weak until the missing receipts bind to A_core/B_context facts.
- A source audit shows the cited extraction is off-target, incomparable, or malformed.

## What would weaken this

- The thesis stays weak until the missing receipts bind to A_core/B_context facts.
- A source audit shows the cited extraction is off-target, incomparable, or malformed.

## Strongest counter-evidence

- _No direct opposing receipt was selected by this run. Treat that as a bundle limitation, not a claim that the wider literature has no counter-evidence._
