Preoperative thrombocytosis may identify patients who are at greater risk for advanced disease, unfavorable grade histology, and recurrence.

There are several potential risks. Should it be risk or risks?

  • 1
    Do you mean that to be "advanced disease, unfavorable grade histology, AND recurrence"--or do you mean it to be "advanced disease, unfavorable grade histology, OR recurrence"? You need to choose one of those two possible coordinating conjunctions (either "and" or "or") to end the list of outcomes being discussed. – Shosht Sep 28 '17 at 5:38
  • and - does it make a difference in risk or risks? – JuanTamad Sep 28 '17 at 5:53
  • Patients might face risks or be at risk. Either way, neither would be for; only of or from. This is a risk for people is too different from people are at risk for (anything). Whether it should be … histology, and recurrence depends on how many conditions or risks are being listed. 1) advanced disease 2) unfavorable grade histology 3) recurrence or what, please? – Robbie Goodwin Sep 29 '17 at 17:16
  • I posted a question to the meta forum concerning the original question here. – Shosht Sep 29 '17 at 21:59
  • @Robbie Goodwin Try a Google Ngram on "at risk for" and "at risk of". And I'd say recurrence of what is obvious--the original disease, post op thrombocytosis. – Xanne Sep 30 '17 at 6:30

Use at ... risk even if multiple possible consequences are listed. See the example I've shown in the following dictionary entry:

at risk phrase Exposed to harm or danger. ‘Children who use mobile phones are at risk of memory loss, sleeping disorders and other health problems.’ - ODO
