Likelihood ratio (i.e., SSLR) computed by the formula, where x1 is the number of men in a particular self-reported ED stratum with ED by urologic examination, n1 is the total number with ED by urologic examination, x0 is the number of men in the same self-reported ED stratum without ED by urologic examination, and n0 is the total number of men without ED by urologic evaluation
ED, erectile dysfunction; SSLR, stratum-specific likelihood ratio
