Of course, our estimate of direct replication articles provides only one indicator of how much the field values and incentivises this type of self-correction (other indicators like funding and the impact of replications are also relevant to consider). (7/9)

This estimate doesn’t include: conceptual replications, articles where the replication was not a main contribution of the article, direct replications that are published in lower impact journals, preprints, or replications that are never published. (8/9)
