Many kidney dialysis patients get vitamin D injections to correct for a lack of calcium. Two forms of vitamin D injections are used: calcitriol and paricalcitol. In the first study to compare survival rates of patients getting one drug or the other, the records of 67,000 dialysis patients were examined. Half received one drug; the other half the other drug. After three years, 58.7% of those getting paricalcitol had survived, while only 51.5% of those getting calcitriol had survived. What percent of the survivors had received paricalcitol? Construct an approximate two-way table of the data (due to rounding of the percentages we can’t recover the exact frequency counts).
