作为正在进行的工作的一部分，对我们的有限元（FE）模型的进一步分析显示，在我们的原始分析中，所有30个模型都存在系统性错误。在所有30个FE模型中，用于表示颞肌最大等长收缩的力大小是正确值的三分之一。所有30个FE模型中所有其他肌肉的力均为正确值的一半。该错误代表FE建模阶段的人为错误，而不是解剖重建或多体动力学建模中的错误。因此，所有其他非FE结果（原始文章中的图2-4）不受影响。在这里，我们提出了修正的结果，以取代图5和电子补充材料中的绝对值，图S5在原来的文章。如下文和电子补充材料中所示，贯穿所有30个FE模型的误差的系统性意味着只有绝对应力值受到影响。在我们的研究中，相对值以及模型之间的比较和从中得出的所有结论都不受误差的影响。
Further analysis of our finite element (FE) models, as part of ongoing work, has revealed a systematic error running through all 30 models in our original analysis. In all 30 FE models, the force magnitudes applied to represent maximum isometric contraction of the temporalis muscle were one-third the correct values. The forces for all other muscles in all 30 FE models were half the correct values. This mistake represents human error in the FE modelling stage rather than errors in the anatomical reconstructions or multi-body dynamics modelling. All other non-FE results (figs 2–4 in the original article) are thus unaffected. Here, we present corrected results to replace the absolute values presented in figure 5 and electronic supplementary material, figure S5 in the original article. As demonstrated below and in the electronic supplementary material, the systematic nature of the error running through all 30 FE models means that only the absolute stress values are affected. The relative values and therefore the comparisons across models and all conclusions drawn from them in our study are not impacted by the error.
