Baseline hemoglobin (Hb) was positively associated with subsequent Hb. Each 1\u202fg\/dL increase in baseline Hb predicted a\u00a00.73\u202fg\/dL increase in Hb during treatment (95% confidence interval [CI] 0.7\u20130.76). Male sex was associated with a\u00a00.16\u202fg\/dL higher Hb (95% CI 0.04\u20130.29), while female sex showed the opposite trend. CCRT was associated with a\u00a00.18\u202fg\/dL reduction in Hb (95% CI \u22120.33 to \u22120.03). Radiotherapy to the pelvis, bone, and head and neck regions resulted in Hb reductions of 0.18, 0.34, and 0.94\u202fg\/dL, respectively (95% CI \u22120.33 to \u22120.03, \u22120.53 to \u22120.15, and \u22121.26 to \u22120.62, respectively), while brain irradiation increased Hb by 0.22\u202fg\/dL (95% CI 0.05\u20130.38). Age, cumulative dose, and thoracic irradiation did not show a\u00a0significant correlation with Hb changes. Adjusted R\u2011squared for the development and validation data were 0.6 and 0.71 for Hb, 0.42 and 0.11 for white blood cell count, 0.36 and 0.32 for neutrophils, 0.42 and 0.06 for absolute neutrophil count, and 0.43 and 0.36 for platelets, respectively.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Hb levels during radiotherapy could be explained using linear regression, although they did not negatively correlate with cumulative dose.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s00066-024-02344-1","type":"journal-article","created":{"date-parts":[[2025,1,10]],"date-time":"2025-01-10T13:46:03Z","timestamp":1736516763000},"page":"561-566","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Linear regression analysis for complete blood count parameters during radiotherapy"],"prefix":"10.1007","volume":"201","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3924-1210","authenticated-orcid":false,"given":"Aniwat","family":"Berpan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nattapatch","family":"Janhom","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,1,10]]},"reference":[{"issue":"8","key":"2344_CR1","doi-asserted-by":"publisher","first-page":"1528","DOI":"10.1002\/(SICI)1097-0142(19991015)86:8<1528::AID-CNCR20>3.0.CO;2-E","volume":"86","author":"M Grogan","year":"1999","unstructured":"Grogan\u00a0M, Thomas\u00a0GM, Melamed\u00a0I, Wong\u00a0FL, Pearcey\u00a0RG, Joseph\u00a0PK, Portelance\u00a0L, Crook\u00a0J, Jones\u00a0KD (1999) The importance of hemoglobin levels during radiotherapy for carcinoma of the cervix.
