How to Catch Value from Query?

I have Query :
$myset = $wpdb->get_results( “SELECT MAX(visits) FROM we_win_visits WHERE user_id=’$u_id’ AND les_id=’$postid'”);

Which Output Like

Array
(
    [0] => stdClass Object
        (
            [MAX(visits)] => 6
        )

)

How to Catch “6” from this query as a String , so I can compare

if ($string <= Catch Value)
{
//Do Code
}
Else
{
//Exit
}
