Random Pubmed Citation(s) Generation

Sorry for the very slow response. I must have missed the post notification email.

The random feature only shows one reference out of a list of n returned by the query, if you use -n as the limit.

You could put the shortcode in 4 times, but there would be no guarantee of not getting the same reference more than once.

WP Pubmed Reflist doesn’t currently do what you want, but I will try to add that to a future version (no promises about how fast that will happen!)
