The percentage reduction in Ef due to 12 days of refrigeration at $4°C$ is reported incorrectly in the text of both the Abstract and the Results (Sec. 3.2) (1). The published text states that Ef is reduced to $3.1±41.3%$ of control values: “…Ef (to $3.1±41.3%$ of control values, $p=0.046$)…” (p. 064502-1), and “By day 12, Ef decreased to $3.1±41.3%$ ($mean±95%$ CI)” (p. 064502-3). Please note that the decimal point is incorrectly placed, and Ef was in fact reduced to $31.3±41.3%$ of control values. This percentage is consistent with the reduction in Ef illustrated in Fig. 3(c) (1).
