The formula is \frac{(140 - \text{age}) \times \text{weight}}{0.81 \times \text{creatinine}} \times S, where S is 1 for males and 0.85 for females.

1	estimate_gfr_cockcroft(creatinine, age, is_female, weight)

`creatinine`	Creatinine (\text{μmol} \text{l}^{-1}).
`age`	Age (years).
`is_female`	`TRUE` if patient is female, `FALSE` if patient is male.
`weight`	Weight (kg).

eGFR (\text{ml} \text{min}^{-1}), or NA if any parameters are NA.

Creatinine clearance may overestimate glomerular filtration rate in kidney injury. In non-ideal body composition, Cockcroft-Gault formula may be (increasingly) inaccurate. Note that the eGFR provided by this formula is not normalised for a standardised body surface area of 1.73 m^2 - to achieve this, divide the eGFR by the patients body surface area (using your method of choice) and multiply by 1.73 m^2.
