“…In a previous study on Iranian male workers, the hand length was obtained 193.01 mm, which was smaller than the hands of car mechanics and farmers of this study (Mirmohammadi et al, 2016). To investigate the possible differences in hand dimensions between the current study and previously published data, hand data from previous studies involving subjects from North Colombia (Oviedo‐Trespalacios et al, 2017), Korea (Jee & Yun, 2016), Turkey (Cakit et al, 2014), Nigeria (Obi, 2016), Bangladeshis in the USA (Imrhan et al, 2009), Jordan (Mandahawi et al, 2008), Vietnam (Imrhan et al, 1993), and central Iran (Mirmohammadi et al, 2016) were obtained. The mean of hand dimensions and the result of comparisons (Cohen's effect size) are summarized in Table 5.…”
