I tried to make it as legible as possible, and the abbreviations are clear (so "Rom" means Romanian, not the Roma). The accompanying graphic that I dug up online shows the Four Temperaments, which are essentially what the four quadrants of an E x N coordinate plane represent, along with some related characteristics. The list of natural language words that describe personality traits can be factor-analyzed, and this approach yields the same Big Five traits from the NEO-PI (Saucier & Goldberg 2001). A word like "excitable" would load positively on both the E and N factors, for instance. Note also that "anxious" reflects both low E and high N -- most interesting personality phenotypes will be composites like this. However, remember that the EPQ and NEO-PI measure continuously varying traits (the score conveys both direction and magnitude), unlike the typological approach of the Four Temperaments and the psychiatric manual DSM-IV.
Other characteristics don't relate much to E or N -- "dependable" or "orderly" are more related to the Big Five factor Conscientiousness. Recall that the EPQ measures a trait called Psychoticism, which is like the interaction between Big Five Agreeableness and Conscientiouness, but inversely related to them -- that is, someone who scores high on Psychoticism would score low on A and C. This multiplicative interaction will skew the distribution much more so than if just A or C or an additive interaction were chosen, and sure enough, in the chart below, notice that the scores on Psychoticism are much lower across countries than on E or N -- the highest score is 9.1, which is barely at the minimum score on either E or N, indicating that the bulk of the Psychoticism distribution is packed into the low end. And unfortunately, you can't decompose a product into a unique pair of multiplicands, so if one person's (or country's) Psychoticism score is higher than another's, that could be because of higher A and equal C, vice versa, or higher scores on both. Having said that, here is the list of Psychoticism scores, in descending order, from the studies synthesized by Lynn & Martin:
