Calculate proteinuria categories

Usage

nephro.proteinuria_category(
  proteinuria,
  proteinuria_units = "mg/g",
  semiquantitative_values = "forbidden"
)

Arguments

proteinuria: Numeric vector. Urine protein, could be expressed in "mg/day" (24-hour urine collection), "mg/mmol" (UPCR) or "mg/g" (UPCR). Units of measurement should be defined in variable proteinuria_units (if not defined explicitly by user, the default value is "mg/g").
proteinuria_units: Character string. Units in which urine protein is measured. Could be one of the following: "mg/day", "mg/mmol" or "mg/g".
semiquantitative_values: Character string. Defines whether semiquantitative values are allowed in the data. If "any", all semiquantitative values ('<30', '30-300', '>300') and any numeric values (29, 30, 35, etc) will be classified into A categories (NB! both '30-300' and '30-299' will be classified as A2). If "only_limits", only limiting semiquantitative values ('<30', '>300') will be classified into A categories, but middle semiquantitative values ('30-300') will be omitted; but numeric values (29, 30, 35, etc) will be classified into A categories. If "forbidden", only numeric values will be classified into A categories.

Value

string albuminuria category.

Details
