“…Station 7 was reported as the main predictor in three studies [16,17,18], station 4R in two studies [17,19], hilar stations in two studies [20,21], station 3p in one study [22] and station 4 (4R + 4L) in three studies [16,23,24]. Two studies [25,26] did not find any significant statistical difference. Six studies analyzed lymph node station as the predictor in patients with suspected sarcoidosis [27,28,29,30,31,32], but each one reported different results and the only investigation reporting statistical analysis showed no difference among the stations sampled [30].…”
