Table 3 Result of subgroup analysis among EBUS-TBNA procedures for LNs >  10 mm and ≤ 10 mm in diameter

From: Randomized controlled trial to evaluate the utility of suction and inner-stylet of EBUS-TBNA for mediastinal and hilar lymphadenopathy

Compared procedures Subgroup Pa value
LN size, mm adequacy rate diagnostic yield
suction–stylet vs. no-stylet ≤ 10 >  0.999 >  0.999
> 10 0.754 >  0.999
suction–stylet vs. no-suction ≤ 10 >  0.999 0.289
> 10 0.523 >  0.999
