Figure 4.

Volcano plot for the ratio of predicted and expected date versus the probability of being late for each trial. The volcano plot shows a scatterplot with X-axis is the ratios between the predicted completion dates $T_{Pred}$ and the expected completion dates $T$ with $\left(T_{Pred}-T\right)/T$, and the Y-axis is the probabilities of being late $P_{Late}$ (y-axis) for each clinical trial.
