Figure 1. Exposure-response relationship between arsenic in drinking water and diabetes by NOTCH2 in Dhaka, Bangladesh, 2001–2011.

Figure 1

Restricted analyses were performed among people exposed to water arsenic below 148 μg/L adjusting for age, sex, BMI, smoking, skin lesion, and arsenic in drinking water using cubic polynomial models. P for interaction was 0.012. Sample sizes were 316 for TT carriers and 325 for TC/CC carriers of rs699780. The solid line indicated the estimated odds ratio using lowest exposure levels of water arsenic as the reference. Water arsenic was natural logarithm- transformed.
