Coefficients of the logistic regression, y = 1/(1 + Exp(β 0+β 1 x)), showing the probability of live birth as a function of the confidence score, which is the AI‐generated predicted probability of live birth obtained from an image of the blastocyst

β 0, β 1, coefficients; SE, standard error; x, confidence score of the blastocyst; y, probability of live birth.
