Fig. 6From: CT comparison of the nasal airway anterior and posterior to the piriform aperture in patients with and without nasal obstructionBoxplots of the ratios of the anterior (CT-CSAant−30) to the posterior noses (CT-CSApost−80). The latter was significantly lower in cases (median value: 0.84) than in controls (1.00; p = 0.006). X-Axis: Subject type; Y-Axis: Ratio (CT-CSAant−30/CT-CSApost−80).Back to article page
