Differences bat these were male count was significantly lower (1% level) than the female count. There was no evidence at the 1% level that any of the two- or three-factor interactions (years, sex, exposed versus Nonexposed, age groups) were significant. For lymphocytes there was evidence at the 5% level of an interaction between exposure and sex, and for neutrophils there was evidence at the 5% level of an interaction between exposure pong the compnt decrease in rved for the ex- and year, The four-factor interaction was treated as ¢rror, an assumption which appeared justified upon examination of the variances. Since these data are being further analyzed, no interpretation as to biological significance of the above interactions is justified at present.” PE nonexposed, + decrease in . 2 “t “wn \ my a a ~~ a 4 10 .
