## Finding Studies on PubMed

PubMed is a free database of biomedical literature maintained by the National Library of Medicine. To locate studies, enter key terms such as peptide names or mechanisms into the search box on https://pubmed.ncbi.nlm.nih.gov/ and press enter. Results can be filtered by publication date, article type, or species using sidebar options. (mechanistic, source_ids: ["s1"])

## Reading the Abstract

Abstracts summarize objectives, methods, results, and conclusions. Begin by reviewing the conclusions section, then methods, then results. This approach allows efficient evaluation without reading the full text if details are insufficient. (mechanistic, source_ids: ["s2"])

## In Vitro vs In Vivo Studies

In vitro studies occur in controlled lab environments such as cell cultures or test tubes. In vivo studies involve living organisms. In vitro results provide cellular-level data but do not replicate whole-organism responses. (mechanistic, source_ids: ["s3"])

## Rat Studies vs Human Trials

Rat studies represent preclinical research and often show tissue repair or inflammatory modulation in animal models. Human clinical trials provide direct evidence of effects in people. Translation from rat to human data is limited; animal models frequently fail to predict human outcomes, with low success rates in progressing to approved interventions. (preclinical for rat data; human for trials, source_ids: ["s4"])

## Anecdotal Reports vs Controlled Data

User reports on forums or social media constitute anecdotal evidence and lack controlled conditions or verification. These differ from both preclinical animal data and human trials. (anecdotal, source_ids: [])

## Evidence Tiers and Framing

Claims are graded by data source: human (randomized trials or clinical data), preclinical (animal or cell studies), mechanistic (in vitro or pathway descriptions), anecdotal (self-reports), or speculative (extrapolations without direct data). Where relevant, distinguish repair processes (e.g., vessel or collagen formation) from suppression mechanisms. No human data exists for many peptide mechanisms listed in definitions.
