метод Герасимова рулит

В продолжение темы о корреляции костной и мышечной ткани - наткнулся на статью в ПабМеде, где сравнивали разные методы восстановления. Оказалось, что метод Герасимова до сих пор самый лучший:


This paper tests six methods of predicting external nasal profile proportions, using the form and dimensions of the bony nasal (piriform) aperture. A sample of 122 lateral cephalograms was measured and traced before each method was attempted, under blind conditions where appropriate. Error was assessed by comparing predicted to actual proportions. Methods used by the following authors were tested: Krogman and Iscan (1986 The Human Skeleton in Forensic Medicine, Springfield: C.C. Thomas), Gerasimov (1955 The Reconstruction of the Face on the Skull), Prokopec and Ubelaker (2002 Forensic Sci. Commun. 4:1-4), Macho (1986 J. Forensic Sci. 31:1391-1403), George (1987 J. Forensic Sci. 32:1305-1330), and Stephan et al. (2003 Am J. Phys. Anthropol. 122:240-250). The two-tangent method by Gerasimov (1955 The Reconstruction of the Face on the Skull) was found to perform best at predicting a point on the nasal tip on male and female preoperative subjects. The method of Krogman and Iscan (1986 The Human Skeleton in Forensic Medicine, Springfield: C.C. Thomas) performed poorly, as did the nasal profile determination method (Prokopec and Ubelaker 2002 Forensic Sci. Commun. 4:1-4). The other methods, all derived by a process of regression calculations, were shown to perform with variable accuracy on this sample, despite the age range and ethnicity of this sample closely resembling that of the samples from which these methods were derived.

Что интересно: автор одной из свежих статей (Prokopec and Ubelaker (2002)) - ученик ученицы Герасимова. Получается, наука за 50 лет двинулась не вперёд а назад.

Наука потопталась вокруг и не нашла ничего лучшего :)

Мне кажется, что качественно и беспристрастно проведённое сравнение методов - это тоже наука. Ок, без инсайтов оно может и не так ярко смотрится, но даёт ценную пищу для тех, кто может инсайтить.
