Preoperative GPT

Preoperative GPT (clinical table).

Name in the dataset preop_alt
Type clinical
Stored in clinical_data.csv
Unit IU/L

Description

Pre-operative copy of a lab result; behaves like the lab data.

Measurement space

-0.500.5true minus recorded (IU/L)density

A vertical slice through the measurement space: how the true value is spread around any one recorded value. Its shape is uniform.

Time

This variable carries no time of its own in the dataset.

Value

Model kind uniform: single resolution; uniform over the rounding interval
Resolution 1 IU/L, nearest
Native step 1 IU/L
Anchor nearest (convention)

In this release

How wide the true-value distribution is, record by record, over 6,024 of 6,388 records (all clinical rows) that have one. Computed with the pinned model, aggregates only.

Median p10 to p90
Standard deviation 0.289 IU/L 0.289 to 0.289 IU/L
95% interval width 0.95 IU/L 0.95 to 0.95 IU/L
Mean minus recorded 0 IU/L 0 to 0 IU/L

Anchor

Laboratory results rounded to the last reported digit; at most half the last digit. See what an anchor is and every variable's anchor.
