Does anyone have a copy of Sample size tables for clinical studies. Oxford, Blackwell, 1997? I need to know whether Table 3.1 is labelled "Sample sizes for comparison of proportions" and whether Machin D, Campbell MJ, Fayers P and Pinol APY are the editors/authors of the volume or the chapter in which table 3.1 appears.
