From: Handgrip strength during admission for COPD exacerbation: impact on further exacerbation risk
Rate of exacerbations requiring emergency room visit and admission within three, six, nine, and twelve months of the index admission. Abbreviation: ER: emergency room; HGSw: handgrip strength weakness. (A) The rates of emergency room visits within 6, 9, and 12 months after index admission were significantly higher in the HGSw group than in the non-HGSw group. (B) It did not achieve significant differences in the readmission rates within 3, 6, 9 or 12 months between HGSw and non-HGSw groups. There was a trend to have higher admission rate within 9 and 12 months in HGSw group, even though there was no statistical significance
