Display studies not contributing data on forest plots
As an authors, I would like to highlight studies that did not report key outcomes by displaying those studies on the forest plot with no data (instead of the current zeroes - or maybe with just the n per group), so that my readers have a sense of the amount of missing data and the potential for selective reporting bias. This idea arose in a workshop at the Australasian Cochrane Symposium on risk of bias led by Julian Higgins.
Pros: +3 High value;
Cons: -1 Hard to do (cannot do until new review format)
