Values are numbers of patients among 62 with MRI finding that given compartment was involved with tenosynovitis. ECU = extensor carpi ulnaris, APL = abductor pollicis longus, EPB = extensor pollicis brevis, ECRB = extensor carpi radialis brevis, ECRL = extensor carpi radialis longus, EPL = extensor pollicis longus.
