Effects of Temperature during in vitro culture and HSP70 addition in the IMC medium on blastocyst formation rates on days 7, 8 and 9.

Stage of Embryos	Factor	B- Coefficients with 95% CI	Sig.
Day-7 blastocysts	Temperature	−9.1 (−10.7, −7.6)	<0.001
	HSP70	3.9 (0.8, 6.9)	0.017
Day-8 blastocysts	Temperature	−10.0 (−12.5, −7.5)	<0.001
	HSP70	4.1 (−0.8, 9.0)	0.096
Day-9 blastocysts	Temperature	−9.9 (−12.2, −7.5)	<0.001
	HSP70	4.8 (0.2, 9.5)	0.043

Multiple regression (Dependent variable: embryo development rates on days 7, 8, 9, respectively and independent variables: Temperature and HSP70).
