Table 2. Pulmonary nodule characteristics by sex (n=219).

Variables	Males (n=114)	Females (n=105)	Overall (n=219)
Number of nodules per patient	5.00 [2]	5.00 [3]	5.00 [2]
Largest nodule size (mm)	5.00 [3]	5.00 [3]	5.00 [3]
Number right upper lobe	52 (45.61)	51 (49.04)	103 (47.25)
Number right middle lobe	9 (7.89)	8 (7.69)	17 (7.80)
Number right lower lobe	39 (34.21)	35 (33.65)	74 (33.94)
Number left upper lobe	41 (35.96)	46 (44.23)	87 (39.91)
Number left lower lobe	33 (28.95)	30 (28.85)	63 (28.90)

Data are presented as median [interquartile range] or n (%). Lobar distribution is reported as number of patients with nodules in that lobe; totals may exceed 100% because some patients had nodules in multiple lobes.
