Placing a prefix for the distribution function changes it's behavior in the following ways: dxxx(x,) returns the density or the value on the y-axis of a probability distribution for a discrete value of x pxxx(q,) returns the cumulative density function (CDF) or the area under the curve to the left of an x value on a probability distribution curve qxxx(p,) returns the quantile value, i.e. Kidney function is proportional to kidney size, which is proportional to BSA.
