Finding F-1498

“High prevalence of restrictive lung disease (28% among control group and 30% among photocopier operators) was observed.”

Chronic exposure to emissions from photocopiers in copy shops causes oxidative stress and systematic inflammation among photocopier operators in India (2013). Environmental health : a global access science source. Page 5. CKB 6861

Structure

Source: Printers and photocopiers
Outcome: Lung function
Population: photocopier operators
Setting: copy centre
Study design: cross-sectional study of photocopier operators in copy centres against a control group: respiratory symptoms, general health problems and lung function compared between the groups (class 4)
Effect: prevalence 30
Caveat: the study calls both shares high and the difference between them is small
