efficacy of anaesthetic injections[edit]

The section Treatment starts:

Treatment consists of several such anesthetic injections, sometimes combined with corticosteroids. Such an approach yields persistent pain relief in two-thirds of patients. This beneficial effect on pain has been demonstrated in a prospective double blind trial.^[1]

Looking at the referenced study, 13 of 24 patients receiving the anaesthetic injection (lidocaine) evinced significant pain relief compared to 4 of 24 patients receiving a placebo (saline), so I'm confused that the text reports this as benefitting "two-thirds of patients". (I was prompted to check the source after noticing that the text disagreed with the equivalent page at wikipedia.nl, [1], which says instead that one-third of patients were pain-free after the treatment.)

The two-thirds figure and associated reference were added as part of the first version of the page [2], which also appears to be the only contribution ever made by that user. Could someone competent to interpret the results of a placebo-controlled trial please check whether "two-thirds" should be changed to "one-third" or something else?

Oh, I just noticed that the .nl page was made by the same user a few days before they made the .en version, and the discrepancy already existed in those initial versions. I suspect therefore that the Dutch text was original, and an error was made in translating to English (perhaps prompted by the later mention of a two-thirds success rate for the surgical procedure).
