Changes in PASI and serum profile of MMP8 in Ps O group (hashed box) and PsA O group (dotted box). The box and whiskers plot identifies, respectively, the value of the median (intermediate line), the 25^th and 75^th percentile (box), and the minimum and maximum value (whiskers). Asterisks indicate significant intergroup differences (* p < 0.05, ** p < 0.01). MMP: Matrix metalloproteinasis, PASI: Psoriasis area severity index, Ps O: Psoriatic onychopathy, PsA O: Psoriatic arthritis with onychopathy.
