Short answer
Several possible studiesNo clear answer.
More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.
