the correlation coefficient, relative error (RE) and root mean square relative error (RMSRE) was employed and revealed improvement of RE from 25.9 to 6.8 and 3.9% (depending on the correction method) for eGFRScr; from 19 to 8.1 and 3.9% for eGFRScrBS and: from 11.6% to 2.0 and 2.3% for eGFRS3M (respectively). The RMSRE values changed from 30 to 21.3 and 19.8% for eGFRScr, from 25.1 to 21.6 and 19.8% for eGFRScrBS and from 19.1 to 15.8 and 15.3 % for eGFRS3M. Conclusions: Modifications of Schwartz equations at GFR > 60 ml/min/1.73m 2 significantly improves the accuracy of calculating eGFR. The 3-markers equation is more accurate and should be employed frequently.
ARTICLE HISTORY
Zespół Alporta (ZA) i choroba cienkich błon podstawnych (TBMN), jako genetycznie uwarunkowane glomerulopatie, są w wieku dziecięcym trudne do różnicowania i brak jest czynników prognostycznych odległych powikłań. Celem opracowania była analiza porównawcza przebiegu klinicznego i zmian histopatologicznych w biopsji nerki u dzieci z rozpoznanym ZA lub TBMN.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
