Lagging by an average of 20% if they are administered to patients within a year of contracting tuberculosis and by almost 30% if they are administered after a year, tuberculosis treatments in African countries have success rates that continue to be far less than those in other countries, according to the statistics recently released by the World Health Organization.

(B) If administered within a year of patients' contracting tuberculosis, treatments have success rates in African countries lagging behind those in other countries with an average 20% lower, and if administered after a year, they lag by an average 30% lower, according to the World Health Organization's recently released statistics.

(C) The World Health Organization's recently released statistics indicate that treatment success rates for tuberculosis in African countries continue to lag far behind those in other countries, by an average of 20% if treatments are administered within a year of patients' contracting the disease and by almost 30% if they are administered after a year.

(D) Recently released by the World Health Organization, statistics about treatment success rates for tuberculosis indicated that African countries were lagging by an average of 20% behind those of other countries when treatments were administered to patients within a year of contracting the disease; the average rates for these countries lagged by almost 30% behind when administered after a year.
