A fact or piece of data from a study of a large quantity of numerical data. A mathematical or quantified characteristic of a group of observations.

A description of the content value of the statistic.

Footnotes and/or explanatory notes.

Type of statistic, eg relative risk.

Statistic value.

The number of events associated with the statistic.

When the number of events is the statistic, use Statistic.quantity and set Statistic.type.coding.code=C25463 and Statistic.type.coding.display=Count. When the statistic is a Proportion, use Statistic.numberOfEvents instead of Statistic.sampleSize.numeratorCount and enter an integer as the value. When the statistic is an Event Rate (where individual participants may have 2 or more events), use Statistic.numberOfEvents to record the total number of events rather than the number of participants with events. When the statistic is any statistic associated with a number of events expressed as an integer, use Statistic.numberOfEvents instead of Statistic.sampleSize.numeratorCount and enter an integer as the value.

Number of samples in the statistic.

Human-readable summary of population sample size.

Footnote or explanatory note about the sample size.

Number of participants in the population.

A human-readable string to clarify or explain concepts about the sample size.

Number of participants with known results for measured variables.

A statistical attribute of the statistic such as a measure of heterogeneity.

Human-readable summary of the estimate.

Footnote or explanatory note about the estimate.

The type of attribute estimate, eg confidence interval or p value.

The singular quantity of the attribute estimate, for attribute estimates represented as single values; also used to report unit of measure.

Often the p value.

Use 95 for a 95% confidence interval.

Lower bound of confidence interval.

A nested attribute estimate; which is the attribute estimate of an attribute estimate.

A nested attribute estimate; which is the attribute estimate of an attribute estimate.

Human-readable summary of the estimate.

The singular quantity of the attribute estimate, for attribute estimates represented as single values; also used to report unit of measure.

Often the pvalue.

Use 95 for a 95% confidence interval.

Lower bound of confidence interval.

A component of the method to generate the statistic.

Description of a component of the method to generate the statistic.

Further specification of the quantified value of the component of the method to generate the statistic.

A variable adjusted for in the adjusted analysis.

Description of the variable.

How the variable is classified for use in adjusted analysis.

Description for grouping of ordinal or polychotomous variables.

Discrete value for grouping of ordinal or polychotomous variables.

Range of values for grouping of ordinal or polychotomous variables.
