For Dan Found all the data for the graph.xlsx from Gestational growth trajectories derived from a dynamic fetal–placental scaling law

Fetal trajectories characterizing growth rates <i>in utero</i> have relied primarily on goodness of fit rather than mechanistic properties exhibited <i>in utero</i>. Here, we use a validated fetal–placental allometric scaling law and a first principles differential equations model of placental volume growth to generate biologically meaningful fetal–placental growth curves. The growth curves form the foundation for understanding healthy versus at-risk fetal growth and for identifying the timing of key events <i>in utero</i>.

表征子宫内（in utero）胎儿生长速率的轨迹，既往研究多以拟合优度为核心依据，而非基于子宫内所展现的生物学机制特性。本研究采用经验证的胎儿-胎盘异速标度律（allometric scaling law），以及基于第一性原理的胎盘体积生长微分方程模型，生成了具备明确生物学意义的胎儿-胎盘生长曲线。此类生长曲线可为区分健康与高危胎儿生长状态，以及识别子宫内关键事件的发生时机提供核心研究基础。
