Comparison to Figure 4 in Kijima et al., 2019. The relation of acute serum zinc concentrations to the functional prognosis after SCI in humans. Each row (A–D) is divided into three columns according to the patient’s NLI (cervical, thoracic, and lumbar). (A) The admission serum zinc concentrations (pooled values from admission to 3 days after injury) of the patients with AIS at final follow-up. (B) Scatter plots illustrating the correlations between the ASIA motor score at final follow-up and the serum zinc concentration at admission (Pearson’s correlation coefficient) at admission, 4 h, 9 h, 12 h, 24 h, and 3 days after injury. (C) The results of a non-linear regression analysis of the functional outcomes using the serum zinc concentration at admission (formula y = a × 3 + b × 2 + cx + d), 4 h, 9 h, 12 h, 24 h, and 3 days after injury. (D) The receiver operating characteristics (ROC) curves of the prediction model based on the acute serum zinc concentrations (pooled values from admission to 3 days after injury) for discriminating between the ability to walk independently (with or without an assisting device) or not.
