The use of censored methods has improved the analysis of such reductions compared with crude methods but implies independent censoring. For HIV\u20101 RNA reduction data, the value at which a patient's HIV\u20101 RNA reduction becomes censored is mainly determined by the patient's baseline HIV\u20101 RNA level. We suggest two possibilities based on modification of the redistribution to the right algorithm to handle the situation of dependence either from a single continuous marker, that is, the baseline HIV\u20101 RNA level, or from multiple markers. Two series of simulation, one in the HIV\u20101 RNA setting and one in the classical censoring setting, compared performance of the previous methods with our suggestions. Our proposed estimators show good performances when the dependent censoring is due to LOD. Overall, in the classical censoring setting, our suggestions perform as well as other methods including the Inverse Probability of Censoring Weighted and the Kaplan\u2010Meier imputation with Bootstrap. We applied those estimators to estimate the HIV\u20101 RNA reduction at week 8 of 502 patients who received a raltegravir\u2010containing regimen and to data from the Mayo Clinic trial in primary biliary cirrhosis.<\/jats:p>","DOI":"10.1002\/sim.8455","type":"journal-article","created":{"date-parts":[[2020,1,25]],"date-time":"2020-01-25T02:15:21Z","timestamp":1579918521000},"page":"968-983","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Weighted Kaplan\u2010Meier estimators motivating to estimate HIV\u20101 RNA reduction censored by a limit of detection"],"prefix":"10.1002","volume":"39","author":[{"given":"Isma\u00efl","family":"Ahmed","sequence":"first","affiliation":[{"name":"INSERM, Biostatistics, Biomathematics, Pharmacoepidemiology and Infectious Diseases (B2PHI) UVSQ  Villejuif France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2612-3522","authenticated-orcid":false,"given":"Philippe","family":"Flandre","sequence":"additional","affiliation":[{"name":"INSERM, Institut Pierre Louis d'Epid\u00e9miologie et de Sant\u00e9 Publique (IPLESP) Sorbonne Universit\u00e9  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,1,24]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00042560-199903010-00002"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/QAD.0b013e32833032ed"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/QAI.0000000000001435"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1086\/605024"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.48.12.4687-4692.2004"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.49.5.1739-1744.2005"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.01051-09"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijantimicag.2013.02.016"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781118032985"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-68639-4"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/biomet\/82.3.515"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.2307\/2533151"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.2452"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.3969"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0006-341X.2000.00779.x"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4757-1229-2_14"},{"key":"e_1_2_7_18_1","unstructured":"EfronB.
