However, methodological variability limits reproducibility and complicates translation to human disease. We sought to develop and apply a set of quality metrics that evaluate reproducibility and translational relevance in contemporary TAC studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">Following Preferred Reporting Items for Systematic Reviews and Meta\u2010Analyses guidelines, we reviewed articles with new mouse TAC experiments published between January 1, 2023, and December 31, 2024, across 6 leading cardiovascular journals. Studies were assessed for predefined quality metrics: bias\u2010reduction methods, reporting of TAC pressure gradients, exclusion of outlying gradients, early measurement of TAC severity and cardiac function, inclusion of female mice, and initiation of interventions \u22657\u2009days post\u2010TAC. Reported average peak instantaneous pressure gradients were summarized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">Eighty\u2010nine articles met inclusion criteria. Most (69.7%) reported at least 1 measure to reduce bias. Only 24.7% reported TAC pressure gradients, and 7.9% excluded mice with outlying TAC severity. Early cardiac function was evaluated in 20.2% of articles, and 31.5% initiated at least 1 intervention \u22657\u2009days post TAC. Female mice were included in 28.1% of studies, with greater inclusion in National Institutes of Health\u2010funded articles. Reported average peak instantaneous pressure gradients varied widely (36.8\u2013131\u2009mm\u2009Hg).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">Most contemporary TAC studies do not report or perform key parameters important for experimental reproducibility and translational validity.
