Such regions can indicate not only the extent of likely sampling errors but can also reveal whether for example it is the case that if the estimate for one quantity is unreliable, then the other is also likely to be unreliable.While presenting confidence intervals tend to lead to fewer misinterpretations than p-values, they are still ripe for misuse or bad interpretations.
Group A mean.
