Creatinine clearance

Creatinine clearance (lab table).

Name in the dataset ccr
Type lab
Stored in lab_data.csv
Stamped by Hospital records clock
Unit mL/min

Description

Single resolution; no heaping in the whole-number screen.

Its time is the lab system's result time: see Blood gas result time and Central lab result time.

Measurement space

-0.500.5true minus recorded (mL/min)density

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

Time

Its time side is still to be described.

Value

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

In this release

How wide the true-value distribution is, record by record, over 37 of 37 records (every lab row of 600 random cases) that have one. Computed with the pinned model, aggregates only.

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

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.
