Name in the dataset	`pt%`
Type	lab
Stored in	lab_data.csv
Stamped by	Hospital records clock
Unit	%

Description¶

Computed from a clotting time, so only some values are reachable; the interval runs to the midpoints of the neighbouring reachable values.

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

Time¶

Its time side is still to be described.

Value¶


Model kind	neighbours: computed value; interval to midpoints of neighbouring reachable values
Resolution	computed value: interval to the neighbouring reachable values

In this release¶

How wide the true-value distribution is, record by record, over 1,985 of 1,985 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 %	0.289 to 0.289 %
95% interval width	0.95 %	0.95 to 0.95 %
Mean minus recorded	0 %	0 to 0 %
