Earlier quoted context omitted.
They didn’t say opioids are no better than either acetaminophen or ibuprofen; they said that opioids are no better than the combination of ibuprofen with acetaminophen — something very rarely prescribed (and usually advised against on the labels of both drugs.)
counter-anecdote: my doctor told me to use precisely that combination for severe pain. She said you cannot combine multiple NSAID's (ibuprofen, naproxen, ASA), but you can combine an NSAID with acetaminophen.
I had no idea the labels said otherwise.
I believe the study, but I've also taken opioids for pain and for me personally there's no comparison. Not even close. Placebo?
