To the Editor: In their meta-analysis, Dr Block
and colleagues1 concluded that epidural
analgesia provided improved postoperative pain control compared with parenteral
opiates, as indicated by a summary difference of 10 mm on a 100-mm visual
analogue scale (VAS). We have several concerns about their methods.
First, we question the clinical significance of a 10-mm difference in
VAS, especially given the relatively low baseline values of the VAS.
