schemaCox

Association schema for right-censored Cox regression ("cox")

Column and artifact contract for results of Cox regression on a time-to-event outcome. The optional entry and time.origin columns record delayed entry and the time origin.

Usage

schemaCox()

Value

A PolyGeniusSchema for the "cox" analysis type.

Columns

Column	Status	Type	Meaning
`.fit`	required	integer	Integer key joining the row to the per-fit `$fits` lookup.
`fit.id`	required	character	Identifier of the fit the row came from.
`schema`	required	character	Name of the schema the row follows.
`family`	required	character	Fitted regression or comparison family.
`outcome`	required	character	Outcome label.
`predictor`	required	character	Predictor label.
`interaction`	required	character
`covariates`	required	character	Covariates adjusted for.
`term`	required	character	Coefficient term the row describes.

`formula`	required	character	Model formula of the fit.
`estimate`	required	numeric	Point estimate, on the scale given by `effect.scale`.
`se`	required	numeric	Standard error of the estimate.
`lower`	required	numeric	Lower interval bound.
`upper`	required	numeric	Upper interval bound.
`statistic`	required	numeric	Test statistic.
`pval`	required	numeric	Raw p-value.
`adj.pval`	required	numeric	p-value adjusted within its declared adjustment family.
`adj.family.id`	required	integer	Key into `$indices$multiplicity`, the adjustment family `adj.pval` came from.
`n`	required	numeric	Sample size.
`effect.scale`	required	character	Scale of `estimate`, one of the controlled `effect.scale` vocabulary.
`test`	required	character
`time`	optional	character
`event`	optional	character

`n.events`	optional	numeric	Number of events.
`reference.level`	optional	character
`contrast.level`	optional	character
`entry`	optional	character	Resolved entry-time column name, NA when the fit has no left truncation.
`time.origin`	optional	character	Free-text label for what time = 0 means, used to warn on a mismatch across pooled studies.

Artifacts

Artifact	Status	Federation-safe	Meaning
`observed.curves`	optional	yes	Observed curves per time point and group.
`predicted.curves`	optional	yes	Predicted curves per time point and profile.
`prediction.grid`	optional	yes	Synthetic covariate grid of `grid.resolution` points.
`risk.table`	optional	yes	Per-time-point at-risk, event and censor counts.
`group.summary`	optional	yes	Summary per group.
