A checklist for testing a summary against the paper: the claims worth checking first, the numbers that quietly change meaning, and where explanations usually go wrong.

Why invented references look convincing, the signals that mark them out, and a five-minute check that settles whether a reference exists and supports what it is cited for.
Read a paper's limitations
Separate what a study found from what its design can support, so you cite the finding at the strength the evidence allows.
