Multivariable logistic regression analysis was conducted to determine the individual associations of RAR and sentiment subjectivity scores with 7\u2010day hospital LOS.

Among them, 384 patients (58.63%) had a hospital LOS exceeding 7\u2009days. Multivariable logistic regression revealed that the RAR and the scaled subjectivity were linked to the 7\u2010day hospital LOS. The combination of RAR and subjectivity was significantly associated with the 7\u2010day hospital LOS. Compared to the low subjectivity and low RAR group, the group with high subjectivity and high RAR was identified as a risk factor for a 7\u2010day hospital LOS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>High RAR and high subjectivity were associated with a higher risk of 7\u2010day hospital LOS in IDA patients with CHF, but the two predictors did not interact.
