wordpress - strip out array from wpdb get_col query results? -

how can function return value, rather array?

$results = $newdb->get_col( "select itemid, price $table itemid = $quanid group price order count(*) desc limit 1", 1 ); 

this result when print_r( $result ); :

array ( [0] => 40 )  

this need:

40 

try

$wpdb->get_var()

if have more results one, you'll first one.
