Spearman rho correlation coefficients for blood lead (PbB) level and hearing level (HL) [pure-tone threshold] for 102 ears of Pb-exposed Andean children for the frequencies 1000, 2000, 3000, 4000, 6000 and 8000 Hz. The values for rho are corrected for ties, and the p-values are tied p-values. NS = non-significant
