Multivariable logistic regression models were constructed using backwards elimination to identify predictors of presentation to ANC at \u226516 and \u226524 weeks GA.

Focusing existing Community Health Worker outreach efforts on the populations at greatest risk of delaying care and expanding access to home pregnancy testing may improve early care attendance. While women presenting late to care were less likely to present without an identified obstetric risk factor, lower than expected rates were identified in the study population overall. Health centers may benefit from provider training and standardized screening protocols to improve identification of obstetric risk factors at ANC-1.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1371\/journal.pone.0256415","type":"journal-article","created":{"date-parts":[[2021,8,25]],"date-time":"2021-08-25T13:29:37Z","timestamp":1629898177000},"page":"e0256415","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":17,"title":["Towards stronger antenatal care: Understanding predictors of late presentation to antenatal services and implications for obstetric risk management in Rwanda"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1787-2417","authenticated-orcid":true,"given":"Christina N.","family":"Schmidt","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Butrick","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5988-8874","authenticated-orcid":true,"given":"Sabine","family":"Musange","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathalie","family":"Mulindahabi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dilys","family":"Walker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,8,25]]},"reference":[{"key":"pone.0256415.ref001","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1046\/j.1365-3016.2001.0150s1001.x","article-title":"How effective is antenatal care in preventing maternal mortality and serious morbidity?
