The excess of lymphoma cases in men was conspicuous among PER-exposed workers with the shortest exposure time, i.e. those that had more than one month but less than one year of employment during 1973–1983, yielding an SIR of 6.02 (95% CI 2.21–13.09). Among male workers with the longest duration of PER exposure (5–11 years), the incidence of non-Hodgkin’s lymphoma was slightly higher than expected (SIR 1.59; 95% CI 0.64–3.27), while among male laundry workers, Ulixertinib cost the incidence of this disease was highest in those exposed for between one and four years (SIR 4.07; 95% CI 1.11–10.42).

As indicated in Table 3, 15 cases of non-Hodgkin’s lymphoma were observed in male workers exposed to PER and Olopatadine of these, eight were employees of companies for which >50% of the cleaning involved use of PER, resulting in an SIR of 3.57 (95% CI 1.54–7.04; not in table). When female workers were similarly classified, seven cases of non-Hodgkin’s lymphoma were noted (SIR 1.58; 95% CI 0.64–3.26). Some details of these individual cases, including occupational title, duration of employment, age at diagnosis and pathoanatomical classification (as recorded in the cancer register), are PS-341 purchase displayed in Table 5, but there was no clear evidence to suggest an association with PER exposure.
