Evidence summary

Nutrition therapy & survival in head and neck cancer

Frontiers in Oncology · ~5 min read

MODERATE

The clinical focus is almost entirely on the drug. Nutritional support tends to be a secondary track, if it's there at all. This retrospective cohort asks: what if how long it continues actually shifts survival?

FindingPatients who received nutrition therapy for longer than four weeks had improved survival compared with those who received it for shorter durations — an association, not a causal effect…

How It Works

STEP 01

Upload

Drop in any scientific publication. We detect the license, check retraction status, and extract structured evidence.

STEP 02

Configure

Set the length, intent, and evidence depth. Plus and Pro unlock advanced controls — statistics detail, domain add-ons, and attribution modes.

STEP 03

Constrain

The evidence engine determines what can and cannot be said. Study design sets the claim level. Not the AI — the methodology.

STEP 04

Review & Export

The compliance badge shows exactly what was checked. Copy, export, or listen — your evidence summary is ready to cite.

Why Ordestra

Other tools summarize. Ordestra constrains. The difference matters when evidence integrity is non-negotiable.

Evidence-Locked

Generated from structured evidence extraction, not free-form summarization. Every claim traces back to the paper.

Claim Discipline

Study design determines language. Observational studies get association language. Controlled experiments get causal language. Always.

Audit-Ready

10 compliance checks run on every output — 9 deterministic rules plus an LLM consistency check. The badge tells you exactly what passed and what needs your eye. Trace any claim back to the source paper in seconds.
