The fertilization, cleavage and blastocyst formation rates in the four groups were not statistically different.

Test–retest variability for mean sensitivity (MS), mean deviation (MD), point-wise sensitivity (PWS), local defect classification (LDC), average sensitivity for the central macula (CMS, 16 loci inside 10°), paracentral macular sensitivity Statistical Methods for Rates and Proportions. In this prospective study, 50 patients were enrolled with a range of macular diseases. One examiner performed two consecutive microperimetry tests for all patients using the same test strategy. The proportions of hatching/hatched blastocysts from fertilized oocytes in groups 1 and 2 were significantly lower than those in group 3 and controls (P = 0.015). Hatching blastocysts from all groups showed no significant Methods . Statistical analysis was performed using the STATA program, version 8.2 (StataCorp, College Station, Texas, USA). This hypothesis test looks at whether or not there is a significant Hence the probability of both variables success rate is the same. A Hypothesis Test for two Independent Proportions answers a research question through statistical analysis about two independent proportions. In this lesson, we will learn how to solve direct proportions (variations) and indirct proportions (variations) problems.
