the word "revise"
For some job seekers, August was not a good month. Hiring fell to the slowest pace in eight months, and the previous estimate for June was revised lower by 28,000 jobs.
But if financial markets were worried, it didn’t show.
Should I put a comma between "revised" and "lower by"? And how to analyse the grammar of "and the previous estimate for June was revised lower by 28,000 jobs"? What does "were worried" in this context?

Question

Answer

I would say "revised down by 28,000 jobs". The sentence would work (I think) if you put a comma between revised and lower, but I think "revised down by..." is just clearer and simpler.

"were worried", in this case is saying that financial markets seemed to not be worried at all, while the author is suggesting/intimating that perhaps there would be reason to worry.
