As the confidence intervals of the two estimated effect sizes overlap, can I assume that the difference between them is not statistically significant (see output)?

Code:

```
Cohen's d
d estimate: 1.320214 (large)
95 percent confidence interval:
lower upper
1.055358 1.585070
Cohen's d
d estimate: 1.744894 (large)
95 percent confidence interval:
lower upper
1.416700 2.073088
