Efficacy and Safety of Loxoprofen Hydrogel Transdermal Patch Versus Loxoprofen Tablet in Chinese Patients with Myalgia: A Double-Blind, Double-Dummy, Parallel-Group, Randomized, Controlled, Non-Inferiority Trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectiveLoxoprofen (LOX) is a nonsteroidal anti-inflammatory drug (NSAID). Although oral administration of LOX has been widely prescribed, clinical guidelines for osteoarthritis generally recommend topical rather than oral NSAIDs in specific patients. However, there is limited information on the effects of loxoprofen sodium oral (LOX-O) versus loxoprofen sodium hydrogel transdermal patch (LOX-T) in myalgia patients. Hence, this non-inferiority study was designed to compare the efficacy and safety of LOX-O versus LOX-T in Chinese patients with myalgia.
methodsIn this double-blind, double-dummy, parallel-group, randomized controlled trial, 182 Chinese patients were enrolled and randomized equally to either LOX-T or LOX-O treatment for 2 weeks. Patients in the LOX-T group applied one sheet of the active LOX-T once a day on the affected site and took one placebo tablet three times a day immediately after meals, whereas patients in the LOX-O group applied one sheet of the placebo patch once a day and took one active LOX-O three times a day. Primary endpoint was the proportion of patients with 50% overall improvement or higher at the final visit. The cutoff value of a non-inferiority difference was set as - 10%.
resultsIn the full analysis set, the primary endpoint of final efficacy rate was 81.3% (n = 91) in the LOX-T group and 72.2% (n = 88) in the LOX-O group. The difference between the two groups was 9.1% [95% confidence interval (CI) - 3.1 to 21.3%], which showed that LOX-T was non-inferior compared with LOX-O. No serious adverse events occurred in either group.
conclusionsThis trial showed the non-inferiority of LOX-T compared with LOX-O in efficacy and safety in Chinese patients with myalgia. Also, the characteristic features of topical LOX-T, such as better compliance and lower risk-benefit ratio, make it more favorable for clinical practice.
trial registrationThe study was registered in the isrctn.com registry (ISRCTN trial ID: ISRCTN16227145).
