In an article1 titled “Development of novel diagnostic system for pancreatic cancer, including early stages, measuring mRNA of whole blood cells” by Yoshio Sakai, Masao Honda, Shigeyuki Matsui, Osamu Komori, Toshinori Murayama, Tadami Fujiwara, Masaaki Mizuno, Yasuhito Imai, Kenichi Yoshimura, Alessandro Nasti, Takashi Wada, Noriho Iida, Masaaki Kitahara, Rika Horii, Tamai Toshikatsu, Masashi Nishikawa, Hirofumi Okafuji, Eishiro Mizukoshi, Tatsuya Yamashita, Taro Yamashita, Kuniaki Arai, Kazuya Kitamura, Kazunori Kawaguchi, Hajime Takatori, Tetsuro Shimakami, Takeshi Terashima, Tomoyuki Hayashi, Kouki Nio, Shuichi Kaneko, Hokuriku Liver Study Group, the results should be changed as follows:

$$\text{Sum}-\text{value}=\text{intercept + a1*gene1 + a2* gene2}\text{+ ... + a56 * gene56}$$

In the formula above, a_n is a coefficient value for each gene (Table 1); “a1*gene 1 + a2*gene 2 + ……… + a56**gene 56” was determined based on Fisher's linear discriminant, and its threshold was 298.018. To simplify the threshold value as zero by the formula, intercept value, −298.018, in the equation, was mounted. Thus, sum‐values 0 or higher and less than 0 were taken as positive and negative for PDAC, respectively.
