For anyone interested, the following is a study of the Safety and Efficacy of Meloxicam in the Treatment of Osteoarthritis
https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/485487

Meloxicam is commonly used to treat pain associated with OA.

This is only one study as I do not know how to bulk search for efficacy information I have to look on a case by case basis.
But under the efficacy header in that study the following is useful information.


The important bit reads:

"When patients were asked to evaluate their chane in disease status with respect to the start of the trial, the percentage of patients reporting improvement increased as the dosage of meloxicam increased (29.7%, 37.9%, 47.7%, 55.8% and 57.9% for placebo; meloxicam, 3.75, 7.5 and 15 mg/d; and diclofenac, respectively)


So in this study patients 37.9%, 47.7% or 55.8% of patients reported an improvement (and 29.7% on a placebo). So a 75% response rate in the october 1st announcement seems pretty damn good to me.

If you read the study at baseline, 60% of patients were rated as having severe or very severe disease activity by the investigator's assessment of disease activity. At the final visit, the proportion of patients with severe or very severe disease activity in the meloxicam, 7.5- and 15-mg/d, groups had dropped to 12% and 13%, respectively. This agrees with the numbers reported by the patients and still makes our 75% response rate look pretty good.

Disclaimer this is only one study but I do not know where to bulk find efficacy information.
