PHILADELPHIA — Hillary Clinton, in accepting her party’s presidential nomination, described her love of tough issues, saying bluntly that “I sweat the details of policy.”

But she delivered a speech that was remarkably without hard facts.

Much of her address was a mix of descriptions of her upbringing, assertions of her opinions and generalized attacks on Donald J. Trump. She talked about marching “toward a more perfect union” and said Mr. Trump “doesn’t like talking about his plans.”

And even when she said “I love talking about mine,” she offered few concrete numbers or assertions to examine. Instead, she spoke in general terms about making “college tuition-free for the middle class” and giving “a boost” to small businesses.

There were, however, a few factual assertions that could be checked — so we did:

CLAIM: “Children like Ryan kept me going when our plan for universal health care failed, and kept me working with leaders of both parties to help create the Children’s Health Insurance Program that covers eight million kids in our country.”
