Table 2. The relationship between 1-year postoperative hair density, intraoperative hair density, survival rate, and proportion of patients whose 1-year postoperative result was good.

	One-year postoperative hair density		p -Value
	HD ( n  = 6)	LD ( n  = 4)
Intraoperative hair density (FU)	41.1 ± 7.5	24.8 ± 9.4	0.025
Survival rate (%)	64.3 ± 5.2	69.2 ± 6.2	0.286
Postoperative result (good: fair, poor)	5: 1	0: 4	0.047

Abbreviation: FU, follicular unit.

Note: Fisher's exact test was used for comparing the proportion of patients with good results, with the significance threshold set at 5% ( p  < 0.05). LD: low density group (hair density < 20FU/cm ² ) HD: high density group (hair density ≥ 20 FU/cm ² ).
