Study quality and risk of bias were assessed using the National Heart, Lung, and Blood Institute (NHLBI) Study Quality of Assessment Tool. Certainty in evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

A decreased or absent preoperative sensory nerve action potential amplitude (SNAP) showed significance with worse postoperative outcomes. The presence of preoperative conduction block showed significance in higher quality studies. There was limited evidence for slow preoperative motor conduction velocities or preoperative electromyography (EMG) abnormalities and postoperative outcomes. Overall quality assessment demonstrated that two studies had \u201cgood,\u201d four \u201cfair,\u201d and two \u201cpoor\u201d quality of evidence. Certainty in evidence was \u201clow\u201d due to risk of bias.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A decreased or absent preoperative ulnar SNAP may predict worse postoperative outcomes. Per higher quality studies, preoperative conduction block at the elbow may also predict worse postoperative outcomes. Careful interpretation is required with a full understanding of the limited evidence, risk of bias, and low certainty in evidence to support the use of preoperative EDX to predict postoperative outcomes in UNE.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pmrj.12952","type":"journal-article","created":{"date-parts":[[2023,2,2]],"date-time":"2023-02-02T18:25:05Z","timestamp":1675362305000},"page":"1326-1334","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Preoperative electrodiagnostic studies and postoperative outcomes for ulnar mononeuropathy at the elbow: A systematic review"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2725-1825","authenticated-orcid":false,"given":"James B.","family":"Meiling","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin B.","family":"Schappell","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric E.","family":"Twohey","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Larry J.","family":"Prokop","sequence":"additional","affiliation":[{"name":"Mayo Clinic Libraries Mayo Clinic  Rochester Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel M.","family":"Cushman","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation University of Utah School of Medicine  Salt Lake City Utah USA"},{"name":"Department of Orthopaedics University of Utah School of Medicine  Salt Lake City Utah USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,2,24]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucli.2006.08.013"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20093"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mcna.2018.10.012"},{"issue":"3","key":"e_1_2_8_5_1","first-page":"408","article-title":"American Association of Electrodiagnostic Medicine, American Academy of Neurology, American Academy of Physical Medicine and Rehabilitation","volume":"22","author":"Practice parameter for electrodiagnostic studies in ulnar neuropathy at the elbow: summary statement","year":"1999","journal-title":"Muscle Nerve"},{"issue":"11","key":"e_1_2_8_6_1","article-title":"Treatment for ulnar neuropathy at the elbow","volume":"11","author":"Caliandro P","year":"2016","journal-title":"Cochrane Database Syst Rev"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.n71"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.32B3.293"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0274(199606)29:6<602::AID-AJIM4>3.0.CO;2-L"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2474-7-44"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(89)80046-2"},{"key":"e_1_2_8_12_1","unstructured":"Council SHPNIMR Special Report Series LH."},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1973.38.6.0780"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0266-7681(05)80126-3"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2474-14-146"},{"key":"e_1_2_8_16_1","unstructured":"Institute NHLB.
