P value=0.0001; Hospital controls SCE: OR=1.1; Family controls=1.5; Case/control: OR=0.28; Depressed SCE levels in 82.6% (176 orchard farmers out of 213 controls/ cases, Whether orchard farmers or non-pesticide exposed) patients predicts even more frequency in orchard-farm workers, though variations in Kashmiris are common
