How to Read the Published Evidence

A short explainer on the fields behind each study in the evidence map: sample size, effect size, follow-up length, and why response and remission are reported separately.

Published July 1, 2026. Back to the research library.

Working draft, staged to exercise the research system. Final copy is pending.

The fields behind each study

Each point in the evidence map carries the same set of fields, so studies can be read the same way.

  • Sample size (n). How many people were in the trial. Larger is not automatically better, but very small samples carry more uncertainty.
  • Effect size (Hedges g). A standardized measure of how large the reported change was. Larger is a stronger reported improvement.
  • Follow-up (weeks). How long people were tracked after treatment. Longer follow-up says more about durability.
  • Response and remission. Response is a meaningful drop in symptoms; remission is falling below a clinical threshold. They are reported separately because a person can respond without reaching remission.

Why we keep the source on every point

This is published, third-party research, shown with its citation. It is not Arcametric outcomes and not a benchmark network. Keeping the source visible is the honesty layer: every claim traces back to a named trial.
