EndNote EndNote How To
1

I put new references in a document that already have some and now I have something like this…

…is a bad prognostic factor (9)(18)(21)

how can I change this for

is a bad prognostic factor (9, 18, 21)

I tried manually but every time I insert a new reference go back to the inicial format.

Thanks a lot

Since I am new using Endnote can you please describe how I do this procedure?

I just have to put the numbers whiout space (eg  (9)(8)(10) …) and them? How I reformat?

Thanks a lot
