  1. GCS, Glasgow coma scale, VSS, Vital Sign Score. The results of Chi-square tests of single VSSinitial criteria are given as odds ratio, Cramer's V (degree of association of single VSS criteria and hospital mortality; 0 denoting no association, 1 denoting maximum association) and significance value.
