Legend: PLTC = platelet count × 1009/L; ESR = erythrocyte sedimentation rate; Hb = haemoglobin; RBC = red blood cells; BS = Barthel Scale; FIM = functional independence measure; standard deviation is reported in brackets; *p < 0.0001 (admission vs. discharge); £p = 0.025 (discharge vs. admission); **p = 0.0001 (discharge vs. admission); ^p < 0.0001 (young vs. old people); & p < 0.0001 (young vs. old people); §p = 0.004 (young compared to old); $p = 0.002 (young compared to old people).
