Urinary Creatinine Concentration

No risk curve catalogued yet.

Urinary Creatinine Concentration by age and sex

Each bar runs from the 5th to the 95th percentile, the darker part from the 25th to the 75th, and the tick is the median. Not a reference range or a target.

The percentiles as a table

Each row is one sex and age band: the values below which 5%, 25%, 50%, 75% and 95% of people fall (mg/dL), from the survey named in the row. Not a reference range or a target.

What studies found when this marker was changed

They describe what happened in those study groups, not a recommendation. See all catalogued interventions.

Each row is one study: what was changed, the effect it reported on this marker, and the source.
