a small trendp = 0.062
At 24 months, a small trend favouring mean thickness was observed in the central condyle (volume: licofelone: -35.1 ± 60.9, naproxen: -46.3 ± 40.0, p = 0.062; mean thickness: licofelone: -0.047 ± 0.096 naproxen: -0.067 ± 0.072, p = 0.040), whereas at 6 and 12 months both methods provided similar findings.
