Value of the index Nash-NashTest for the diagnostic of NASH as stated by the pathologist independent of NAS score. Each index is a specific logistic regression combining parameters weighted according to their diagnostic values. Notched box plots showing the relationship between NAS category (No NASH n = 98), borderline NASH n = 96 and NASH n = 63 and index of No-Nash (Figure 4), index of Borderline-Nash (Figure 5) and index of Nash (Figure 6) and between the pathologist conclusion and index of Nash (Figure 7). The horizontal line inside each box represents the median, and the width of each box the median ± 1.57 interquartile range/√ n (to assess the 95% level of significance between group medians). Failure of the shaded boxes to overlap signifies statistical significance (P < 0.05). The horizontal lines above and below each box encompass the inter-quartile range (from 25^th to 75^th percentile), and the vertical lines from the ends of the box encompass the adjacent values (upper: 75^th percentile plus 1.5 times interquartile range, lower 25^th percentile minus 1.5 times interquartile range).
