The answer in 30 seconds
PDF describes a file format, not the quality of its contents. A report, outdated form and promotional brochure can all appear in the same search results.
Describe the document you want, use filetype:pdf if it helps, then return to the publisher's page to check title, date, version and any later correction.
Examples to adapt
Compare year and version number before using a figure from either report.
Search its exact title to find the publisher's record and related updates.
Record the page and table number so another reader can reproduce the citation.

A checklist to keep

What to check
Download time is not publication time.
A filename can be changed without the content changing.
An isolated copy may lack the most recent correction.
Common questions
Is the first PDF result reliable?
Its position is not evidence; inspect who issued it and which version it is.
What if no author is visible?
Look for the organisation responsible on the publication page; if origin remains uncertain, say so.
