Inter signs synergy graph. Nodes indicate the deficits (codes correspond to the deficits from Methods and [29]) and edges indicate the statistically significant relationships between deficits, i.e. when the conditional probability of one deficit, given another is statistically different (p < 0.05; t-test) from the unconditional probability of the first deficit.
