Correspondence Anesthesiology 2020; 132:1587–618 1599 patient-centered outcomes, will likely not further advance this important field. So although I commend Tran et al. on a comprehensive and excellent dissertation on the transversus abdominis plane block, I suggest that they also push the field forward not just by suggesting that additional trials should be undertaken, but by highlighting the end points that should form the basis for these important trials. There are clearly transversus abdominis plane block–related areas that need further investigation, but they must be done through the right kind of trials.
