Table 5 The table shows the estimates of effect size (Cohen’s d), the sample size and the observed statistical power for the parameters birth weight (BW), placenta weight (PW), mean surface density of PCNA-negative trophoblast nuclei (MD) and nearest neighbor distance of PCNA-negative nuclei (NND).
