Fig. 1From: Effect of recombinant LH supplementation timing on clinical pregnancy outcome in long-acting GnRHa downregulated cyclesA smooth fitting curve analysis between dominant follicle diameter when rLH added and clinical pregnancy rates. The illustrated curved line shows the relation between the dominant follicle diameter when rLH added and clinical pregnancy rates. The area between two dotted lines is expressed as the 95% CI. The clinical pregnancy rate of the patients increased gradually as the dominant follicle diameter when rLH added increasedBack to article page
