In kfre: Kidney Failure Risk Equation (KFRE) Tools

KFRE risk prediction for a single person

Description

Computes the Kidney Failure Risk Equation probability at 2 or 5 years.

Usage

risk_pred_core(
  age,
  sex,
  eGFR,
  uACR,
  is_north_american,
  dm = NULL,
  htn = NULL,
  albumin = NULL,
  phosphorous = NULL,
  bicarbonate = NULL,
  calcium = NULL,
  years = 2
)

Arguments

age	Numeric age in years.
sex	Integer sex indicator, 1 for male, 0 for female.
eGFR	Estimated glomerular filtration rate, mL/min/1.73 \text{m}^{2}.
uACR	Urine albumin to creatinine ratio, mg/g.
is_north_american	Logical, patient from a North American cohort.
dm	Optional integer diabetes indicator, 1 yes, 0 no.
htn	Optional integer hypertension indicator, 1 yes, 0 no.
albumin	Optional serum albumin, g/dL, required for 8 variable model.
phosphorous	Optional serum phosphorus, mg/dL, 8 variable model.
bicarbonate	Optional serum bicarbonate, mmol/L, 8 variable model.
calcium	Optional serum calcium, mg/dL, 8 variable model.
years	Integer, prediction horizon, 2 or 5.

Value

Numeric probability between 0 and 1.
