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).
