Eligible participants included veterans with IDA (defined as hemoglobin &lt;12 g\/dL and either iron saturation &lt;20% or ferritin &lt;50 ng\/mL) who received their first outpatient prescription of oral iron. Patients were further divided into those with NKF (estimated glomerular filtration rate &gt;60 mL\/min\/1.73 m<sup>2<\/sup>) and CKD (estimated glomerular filtration rate \u226515 mL\/min\/1.73 m<sup>2<\/sup>&nbsp;and &lt;60 mL\/min\/1.73 m<sup>2<\/sup>). Data analysis was conducted from February to October 2023.<\/p>\n\n\n\n<p><strong>Exposures<\/strong>&nbsp;&nbsp;Patients were classified into 3 groups based on their oral iron dosing schedule: daily (once a day), multiple doses per day (MDD; \u22652 times per day), or alternate-day dose (ADD).<\/p>\n\n\n\n<p><strong>Main Outcomes and Measures<\/strong>&nbsp;&nbsp;The primary outcomes were change of hemoglobin, ferritin, total iron binding capacity (TIBC), and iron saturation (ISAT), which were calculated with linear mixed-effects models.<\/p>\n\n\n\n<p><strong>Results<\/strong>\u00a0\u00a0A total of 71\u202f677 veterans with IDA (63\u202f202 male [88.2%] and 8475 female [11.8%]; mean [SD] age, 68.47 [13.09] years), including 47\u202f201 with NKF and 24\u202f476 with CKD, were identifed. In patients with NKF in the daily group, hemoglobin increased from baseline (estimated per-30-day difference [SE], 0.27 [0.00] g\/dL;\u00a0<em>P<\/em>\u2009&lt;\u2009.001). In comparison with the daily group, hemoglobin increased more in the MDD group (estimated per-30-day difference [SE], 0.08 [0.03] g\/dL;\u00a0<em>P<\/em>\u2009&lt;\u2009.001), but no difference was noted in the ADD group (estimated per-30-day difference [SE], \u22120.01 [0.01] g\/dL;\u00a0<em>P<\/em>\u2009=\u2009.38). Ferritin, ISAT, and TIBC results were similar, except TIBC showed less change in the ADD group compared with the daily group. Patients with CKD showed similar trends but smaller magnitudes in changes. Among patients with NKF, the adjusted mean increase in hemoglobin was 1.03 g\/dL (95% CI, 1.01-1.06 g\/dL) for those in the daily group, 1.38 g\/dL (95% CI, 1.36-1.40 g\/dL) for those in the MDD group, and 0.93 g\/dL (95% CI, 0.84-1.02 g\/dL) for those in the ADD group at 90 days. Among patients with CKD, the adjusted mean increase in hemoglobin was 0.71 g\/dL (95% CI, 0.68-0.73 g\/dL) for those in the daily group, 0.99 g\/dL (95% CI, 0.97-1.01 g\/dL) for those in the MDD group, and 0.62 g\/dL (95% CI, 0.52-0.73 g\/dL) for those in the ADD group at 90 days.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240487f1_1716387854.30385.png?Expires=1724682816&amp;Signature=2LVim1RMKNVwry7P2upuVwzNy3wAyLPnZuf~w6OOWw0CrXnaWdDGvB~0LKpUiIGjWhC2vmLfx054hgwkYrh3TRd9JGUY9RtdwqTGzuoHDK0dnVwv9U2apThBVShoXBW6ESiy0AYSfdPElbGsRL-UCOgcrA5BcyctTBwOfvhEV2NYRd8jWgS0nM49ZJoQzOlCP-1DAwYueAM-8ke5WqeJW-EceeqHosPt0HvV50AIDlmixLORIGpJWDpMeeD7c72AgUtwe8xwG~UnprXatC~nvJqGWleA2uAYqdc6Dpw5GT5VwwyH-k8Vso~X4wGo95onp1IQVnA1i74CUx39nHe3Ww__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240487f2_1716387854.40492.png?Expires=1724682816&amp;Signature=M~m4GeRhwuNdYfR8qQei1oZItFRLWlfzAEvl7~7y9C6kp7T5c~kIrHcw~h6lbTVYWXTYWiriStcN5QTe6wVQPWwZqM01gIG-umXwmkhCvTB4gstr9Qli3P2uZL67lEhvcmbSaoqZtnYksxWOTAkhE42HcJSDkFcaSPrt137Agx8BiuHFpVSIanz4Lw-FE5~TLJEIk6dNxvbS1j9Lj26itZvpaYCHOwekqa9Hp9t0AZm7cFYxQu2HR0uHWwfEqWrzmFA2eUzMsEmKcZsiN8bgSJ6l5MejjZ69kj4i3rMl8yomqtjLt70cknuCifU-M6YNW4WRT~QSw0HWWpWcWv9fzA__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240487t1_1716387854.28885.png?Expires=1724682816&amp;Signature=gOYr~mKWom7UHSmBHDpZgHuwTr7GfJ1EnWffSrsezfDb0PSqHaYa72IzJaSlQqxmgL9G3NTConnYkr5eZ7xgx6ztEfd3GnEj3-Uv~oCZhrxCz4zAHQ65fP~sI0bvoL5Y8ivWACfY0yvw4XsLKy1p0ah6Zyi~NHrOggbdOgxJqmFw7KyGlAqb6zK6ekFhAcVtf82FYUQtUt3-BYVIUrBa7OUcqRIH48LLp6j6rZg1wwt8QsZ126bFUGVtq6uWeoUB6DvjkFnEjeaG9WKD~0tltonEgQXWs2ZwBz8kwTEfKMwzgTg-xIeRZAK~A8su0LVd5Nn9A4g3wMG6d4Dbm4AVMA__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240487t2_1716387854.35992.png?Expires=1724682816&amp;Signature=28-l7OJK43jnEytYFfuig5iOJN~lZX8oZbt1u~961QVSFmoBL8eLnSUkMEWf6EtWhMKS96-3VDkLLFE3E~rBmY3~4TiPV90iFT1SXVrzQhdKlJFAR~SMqzAdrZQZabT9H8LKqN3I08oQOkh4-ygqEn7iGXgC4d3vy2vrWhX7R2YekQO6RjTLCW9PT09H8~h4M72c5j2DS8HWGacPhA0zGphRYSHJyJSoJaaxDeuPqPwNXqxkmQZ-Rb7UVbrwBtKWQCRlJgvlgVXNfP4pwrsAdcqafjUIv-dkuK49gwg796~MSRnggw72Buc7Lqu3oWk4M7ZWFgzXV0pXofOf2CgulQ__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240487t3_1716387854.41992.png?Expires=1724682816&amp;Signature=5CsK0Z0nHTlkeneuCJJ0A68AX7-eQCcJlZyv5DuZ6uEXsJHifkr~56QhRtxiVA~1oMEGrA6QtMe-jUyQGZIjd8someKll4ifPfn-PJeYBKKXy8QSD46UxhVA4vRR-QXAqqkx6o1BaDuKK-C~nJsS8WwetYnSI3Y8VcXiwJOOddwioZOq8d30bf0F804EkXhA50aA9kkOfwovNYzI6hZBVUHyT7ds~tfuNDQhhwEJJYrI8iE2tbWZNHPaB1zUZ8RufwKdwrtHu-6YZ62iCsXVpQebYZADi0civBBkXbudenB4s4CH0hQhRyvOwCnqxtKWSCJzVEojBUH9Rmt6xSqszw__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong>Conclusions and Relevance<\/strong>&nbsp;&nbsp;In this retrospective cohort study of veterans with IDA, there was no significant difference in the improvement of hemoglobin and iron indices between daily and ADD groups, but quickest improvement was observed in the MDD group.
