Prediction nomogram construction
A nomogram incorporating the above seven independent predictive factors
was built (Figure 1). The length of the variable axis represents
visually the relative contribution of each predictor. Recipient CYP type
of AA and low serum albumin contributed the most points to the model if
present. The nomogram assigned the probability of switching IS drugs by
accumulating the scores of every risk factor detected on the points
scale. The bottom scale showed the
risk of poor curative effects of those recipients who receive an IS
protocol based on TAC by the total score. Higher scores indicated worse
prognosis and clinicians may choose CsA instead of TAC for protocol of
IS initially.
