Which planet do most known extrasolar planet most resemble?

Of what we have found most are the size of Jupiter or larger. But we know many more extrasolar planets exist that we simply cannot detect. If we were to draw hypotheses on what planets are most abundant they would either be similar to dwarf planets. Or, if the reader does not view dwarf planets as true planets then planets the size of ones in the terrestrial zone like: Mercury, Venus, or Earth. Are probably the most abundant.
