Comparison: Tumor vs normal

Case arm

Your requirement
Treatment agent

Comparator

From comparison

Determined by comparison

For treatment vs control, use a named agent, an explicit collection window and an exposed or unexposed state. The comparator needs the opposite reported exposure state for the same agent, target and window.

Other comparisons keep their own normal or healthy comparator requirements. This treatment restriction is not copied to them.

Collection, target and matching

Named agent if supplied; otherwise all interventions.

Scope & matching · additional options

Missing metadata never proves no exposure.

Evidence and comparison rules

Exact results require an eligible sample subset and reported independent subjects in both arms.

“No exposure” applies only to the selected agent, target and time window. No exposure to a new agent before collection does not rule out earlier therapy.

A broader treatment history requires separate, explicit evidence and may be unavailable. All prior therapy requires a through-collection window.

Planned exposure does not establish that treatment occurred. Treatment vs control requires an exposed or unexposed state, a named agent and an explicit collection window.

Organism and specimen requirements apply to both arms. For treatment vs control, disease requirements also apply to both arms.

Genotype requirements Optional Define a requirement, then assign it to samples — Unrestricted
Genotype assignment and variant
Specific protein variant · optional

Leave blank for a gene-level requirement. A variant restriction applies to every selected arm.

Genotype describes sampled material. Confirmed evidence must come from the same samples as your other requirements.

Use with human bulk RNA-seq or expression microarray.

Evidence and comparison rules

Select Homo sapiens and a supported assay in the search filters.

Missing genotype does not establish wild type. Both comparison arms still need eligible, independent samples.

A subject's carrier status does not establish the sampled tumor's genotype or disease.
