Table 3.

Morbidity defined by standard cutoffs versus height-adjusted SDs (measures from all years combined)

	Standard cutoff (N = 387)	> 2 SDs above mean (N = 387)
Left liver enlarged*	4 (1.0%)	28 (7.2%)
Right liver enlarged	6 (1.6%)	36 (9.3%)
Portal vein enlarged	3 (0.8%)	15 (3.9%)
Spleen thickened	5 (1.3%)	10 (2.6%)
Spleen lengthened	2/83† (2.4%)	1/83* (1.2%)

^*Cutoffs for each measure: left liver lobe, > 90 mm; right liver lobe, > 140 mm; portal vein, > 12 mm; spleen thickness, > 40 mm; spleen length, > 120 mm.

^†N = 83 (spleen length was only measured in 2007).
