Hyphens, En Dashes, Em Dashes

Q. Hi! Would “results sharing” be hyphenated in this example? “Each webcast includes in-session polling and results sharing.” Thanks!

Q. Hello! I understand that hyphens work like “treatment-naive patients” but “patients are treatment naive.” However, what would you recommend if the modifier is used alone—e.g., in a graph key? Hyphen or open? Should the key be “Treatment-naive” and “Previously treated,” or “Treatment naive” and “Previously treated”? Thank you!

Q. Hi. I’m working on a label for an image in a printed brochure. The entire label is “bison shoulder blade hoe.” How would you punctuate that—with an en dash (“bison–shoulder blade hoe”)? Or hyphens (“bison-shoulder-blade hoe” or “bison shoulder-blade hoe”)? I was thinking that technically an en dash would be correct according to CMOS 6.80, but that seems too formal and, as CMOS states, unlikely to be noticed by most. There is no room to reword it. Thank you!

Q. Regarding open compounds, would an en dash be correct in “Mr. Potato Head–like head” and “rubbing alcohol–soaked cotton”? Thank you!

Q. Which is correct: “minimum food-safety standards” or “minimum food safety standards”? Thank you.

Q. In your hyphenation guide, adjectival phrases are addressed: “Hyphenated before a noun; usually open after a noun.” Would the adjectival phrase “one-on-one” apply? The dictionary lists it only with hyphens, but I’m dealing with a sentence where it seems the hyphens would be unnecessary: “Coaches are available to meet one-on-one.”

Q. What is the correct way to hyphenate school grade levels, “fifth-grade” or “fifth grade”? And “fifth-grader” or “fifth grader”? Thank you.

Q. I know an en dash separates sports scores, representing the word “to” (e.g., “the Lions won 34–6”), but what about win/loss records? In this case one would say, for example, “They ended the season with a record of 10 and 4.” So should this be expressed with an en dash or a hyphen? 10-4 or 10–4?

Q. I work as an editor, and we use CMOS as our primary source. My boss recently told me to hyphenate “machine-scored” in “the items were machine-scored,” because of a rule she cited about compounds formed with a verb. I can’t find a rule like this in CMOS. Is the hyphen Chicago style?

Q. In my office we have noticed a trend in Merriam-Webster to show previously closed compound words as hyphenated, such as “antiracist” and “antilabor.” CMOS clearly has a spare hyphenation style and lists prefixes as usually closed. Which should we follow when the two sources disagree? I would lean toward continuing to close compounds like “antiracist” and “antilabor” and use CMOS as our source, but we have been going in circles for a year now on this debate. Please help.

Q. CMOS 6.81 says en dashes can be used to set off campuses of universities, as in “University of Wisconsin–Madison.” When abbreviating the university such that it’s one word, would it make sense to change the en dash to a hyphen? For example, would you write “UW-Madison” with a hyphen because “UW” is now one word?
