“…The dosages of NGR1 were 10 μmol/L in two studies (Zhou et al, 2016; Zhou et al, 2017), 20 μmol/L in one study (Yu et al, 2016), and 100 μmol/L in two studies (He et al, 2014; Wan et al, 2015). Cell viability and TUNEL-positive rate were used as outcome measures in six studies (He et al, 2014; Wan et al, 2015; Zhou et al, 2016; Yu et al, 2016; Zhou et al, 2017; Liu et al, 2019), LDH in seven studies (He et al, 2014; Meng et al, 2014; Wang et al, 2016; Zhou et al, 2016; Zhou et al, 2017; Hou et al, 2017; Tu et al, 2018), SOD in three studies (Wan et al, 2015; Zhou et al, 2016; Zhou et al, 2017), and MDA in four studies (Meng et al, 2014; Wan et al, 2015; Zhou et al, 2016; Zhou et al, 2017). The detailed characteristics of the included studies were generalized in Table 2 .…”
