The primary outcome was the pain intensity on posterior portal placement, which was graded as 0 (no pain), 1 (mild pain), or 2 (severe pain). The secondary outcomes were the bilateral pupil diameters measured 30 minutes after ISBPB placement; the incidence of Horner syndrome, defined as a difference in pupil diameter (ipsilateral \u2013 contralateral) of less than \u20130.5 mm; the onset of postoperative pain; and the postoperative numerical rating pain score, where 0 and 10 represent no pain and the worst pain imaginable, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Fewer patients reported mild or severe pain on posterior portal placement in the C5\u2010C8 group than in the C5\u2010C7 group (9 of 36 [25.0%] vs 24 of 37 [64.9%],\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .003).
