Connections between variables: clinical examination (a), pathological examination (b), blood sample (c), cerebrospinal fluid (d). Connections between all variables, calculated by Spearman’s correlation coefficient (numerical variables), Chi2 Test and Cramer’s V (binominal variables) and point-biserial correlation coefficient (connections between numerical and binominal variables). A connection was interpreted as meaningful if the values of the respective correlation coefficients were ≥ 0.4 (light green) and as strong if the values of the respective correlation coefficients were ≥ 0.6 (dark green) and P-values were ≤ 0.05. Negative connections are marked in transparent light and dark green colours, respectively. Due to the high number of variables, the figure is split in four parts according to the health variables under observation: a shows the variables of the clinical observation, b of the pathological examination, c of the blood tests and d of the analysis of the cerebrospinal fluid. Only those variables that had a connection to other variables are shown
