Pain scores were recorded before (NRS<jats:sub>0<\/jats:sub>), 15\u00a0min (NRS<jats:sub>15min<\/jats:sub>), and 4\u00a0weeks (NRS<jats:sub>4w<\/jats:sub>) after treatment using a numerical-rating-scale (NRS; 0, no pain; 10, intolerable pain). Additionally, the PGIC was assessed after 4\u00a0weeks. Two fellowship-trained musculoskeletal radiologists evaluated nerve compression of the injected level and contrast dispersion. Spearman\u2019s rank and point-biserial correlation were applied to assess associations between outcome variables and demographics\/imaging findings. A <jats:italic>p<\/jats:italic>-value\u2009&lt;\u20090.05 was considered to be statistically significant.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>There was a significant positive correlation between immediate pain-relief and longer-term pain-reduction (<jats:italic>r<\/jats:italic>\u2009=\u20090.24, <jats:italic>p<\/jats:italic>\u2009=\u20090.001) with an odds ratio of 2.0 (<jats:italic>CI<\/jats:italic>: 1.1\u20133.6). A good short-term response (NRS<jats:sub>15min<\/jats:sub>\u2009\u2265\u200950% reduction) was associated with a persistent longer-term good response (NRS<jats:sub>4w<\/jats:sub>\u2009\u2265\u200950% reduction) in 59.7% (<jats:italic>CI<\/jats:italic>: 50.9\u201368.0%) of patients. There was no association between short-term pain-relief and PGIC after 4\u00a0weeks (<jats:italic>p<\/jats:italic>\u2009=\u20090.18). Extent and location of nerve compression and contrast dispersion during TFESI did not correlate with longer-term pain-relief (all <jats:italic>p<\/jats:italic>\u2009\u2265\u20090.07).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Our results indicate a significant positive correlation between immediate post-procedural and longer-term pain relief after TFESI in patients with lumbar radiculopathy; however, no effect of short-term pain relief is seen on PGIC after 4\u00a0weeks.
