Word for the extent of truth of an article

I'm looking for a noun to be used in the following sentence to express my uncertainty about the amount of absolute truth an article contains.

In other words, I doubt if the information the article contains are based on facts.

What is the word for the 'degree of truth'?

I am not certain about the _ of this article.

(Sorry I really do not know how I should describe the noun I am looking for.. Using 'degree of truth' to express the idea is a bit strange but I can't think of any other phrase.)

If your concern is with respect to the honesty or bias of the reporting, veracity is probably a good choice.

If your concern is with the rigor or quality of the reporting, then accuracy or reliability are probably the most commonly used terms.

I was going to suggest "verity", but that just means truthfulness. "Accuracy" is another word that came to mind, but it appears as if the first answerer beat me to it.
