Pretreatment HRM achalasia subtypes were determined by the Chicago Classification and JES; Italian and Brazilian classifications were defined by pretreatment esophagram. Post\u2010treatment outcomes were defined using the Eckardt symptom score (good outcome &lt;\u20094) or timed barium esophagram (TBE; good outcome 5\u2010min column height &lt;\u20095\u2009cm).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The Chicago Classification was a significant predictor of symptomatic outcome (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003\u20130.007), whereas JES, Italian, and Brazilian schemes were not. All four classifications were significant predictors of radiographic outcome, with JES demonstrating the best model fit as identified by lowest Akaike information criteria (AIC). Type III achalasia (Chicago Classification) patients had the lowest rates of good symptomatic outcomes despite treatment primarily with POEM, whereas advanced esophagram stages (JES\u2010C, Italian IV, Brazilian 2\u20133) were associated with poorer radiographic outcomes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Both HRM\u2010 and esophagram\u2010based classification schemes predict achalasia treatment outcomes, though with different strengths.
