Preoperative and\n          12-month follow-up data from patients who received CXL plus (n\u2009=\u200996) and CXL only (n\u2009=\u200996) were used in a recursive partitioning approach to construct a frugal tree with three variables\n          (corneal thickness [&gt;\/&lt; 430 um], patient interest in CXL plus [yes\/no], and tomographic cylinder [&lt;\/&gt; 3 D]). In addition, we estimated the probability of the outcome from a\n          multivariate logistic regression model for each combination of variables used in the decision tree.<\/jats:p><jats:p>\n          Results In the complete sample, 101\/192 (52.6%) patients improved by at least two lines at the 12-month follow-up. Patients affirmative in all three answers had a 75.6% (34\/45)\n          probability of gaining at least two lines of improvement in UDVA by CXL plus. The statistical model estimated a 66.0% probability for a successful outcome.<\/jats:p><jats:p>\n          Conclusion A fast and frugal tree consisting of three variables can be used to select a patient group with a high likelihood to benefit from CXL plus. The tree is useful in the\n          preoperative counseling of keratoconus patients contemplating the CXL plus option, an intervention that is not fully covered by many health insurances.<\/jats:p>","DOI":"10.1055\/a-2017-5203","type":"journal-article","created":{"date-parts":[[2023,4,25]],"date-time":"2023-04-25T22:42:48Z","timestamp":1682462568000},"page":"379-384","source":"Crossref","is-referenced-by-count":0,"title":["A Clinical Decision Tree to Support Keratoconus Patients Considering Corneal Cross-Linking Combined with Refractive Treatment"],"prefix":"10.1055","volume":"240","author":[{"given":"Katja","family":"Iselin","sequence":"additional","affiliation":[{"name":"Dept. of Ophthalmology, Lucerne Cantonal Hospital, Lucerne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucas","family":"Bachmann","sequence":"additional","affiliation":[{"name":"Medignition Healthcare Innovations, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Baenninger","sequence":"additional","affiliation":[{"name":"Dept. of Ophthalmology, Lucerne Cantonal Hospital, Lucerne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frantisek","family":"Sanak","sequence":"additional","affiliation":[{"name":"Dept. of Ophthalmology, Lucerne Cantonal Hospital, Lucerne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claude","family":"Kaufmann","sequence":"additional","affiliation":[{"name":"Dept. of Ophthalmology, Lucerne Cantonal Hospital, Lucerne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,4,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"2757","DOI":"10.4103\/ijo.IJO_1841_20","article-title":"Corneal cross-linking (CXL) combined with refractive surgery for the comprehensive management of keratoconus: CXL plus","volume":"68","author":"V P Kankariya","year":"2020","journal-title":"Indian J Ophthalmol"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"2403","DOI":"10.1007\/s10792-020-01394-5","article-title":"Excimer laser treatment combined with riboflavin ultraviolet-A (UVA) collagen crosslinking (CXL) in keratoconus: a literature review","volume":"40","author":"M Ezzeldin","year":"2020","journal-title":"Int Ophthalmol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"423","DOI":"10.2165\/00019053-199915050-00001","article-title":"Pharmacoeconomic evaluation in the real world.
