The chi-square test showed that the rate of reproductive loss differed significantly (p = 0.0369) between the “control” (N = 4) and “exposure” periods (N = 10) and that the number of stillbirths when the level of methemoglobin was increased (>1.5 g/L) during the exposure period was also statistically significant (p = 0.0336). Here, HBG2 is linked to Stillbirth.
