publications - Caption for a figure reproduced from a CC-licensed document

In a research paper for a journal, which uses Science magazine publication style, I'm reproducing a diagram from a document, which has a Creative Commons (CC)-based open document license. The diagram (figure) itself doesn't contain any license references, as is typical for most CC-licensed figures, however the whole original document contains the following statement:

Question: What should be the content and style of the borrowed figure's caption, considering the journal style and the document license? In other words, should it just be (X is reference number)

Figure 1. The title of the figure. Reproduced from Reference X.

or

Figure 1. The title of the figure. Reproduced from Reference X (CC BY-NC 3.0).

or something else?
