No. | First author | Published year | Study design | Patients enrolled | Mean age (Years) | Gender (Male %) | Main findings |
1 | Hye Seon Kang [20] | 2016 | RS | 605 | 69.89 | 85% | The eosinophilic exacerbations had better pulmonary function tests than non-eosinophilic patients with AECOPD (p = 0.004). |
2 | Zheng Qianglin [21] | 2017 | RS | 559 | NA | NA | AECOPD patients had a significantly high prevalence of eosinophilia than non-eosinophilic patients (P < 0.001). |
3 | Meltem Coban Agga [22] | 2017 | RS | 1490 | 66 | 69 | The non-eosinophilic patients with EACOPD had higher of NLR, WBC count and Neutrophil percentage count than in eosinophilic patients (P < 0.00, P < 0.001 and P < 0.001) respectively. |
4 | Robert S. Zeiger [23] | 2017 | RS | 7245 | 71.3 | 57.1% | Patients with greater levels of eosinophilic counts were related to higher frequency of acute exacerbations, increased emergency department visits and hospitalizations (95% CIs, P < 0.001). |
