Since almost a hundred years, psychologists have investigated the link between hand preference and dyslexia. We present a meta-analysis to determine whether there is indeed an increase in atypical hand preference in dyslexia. We included studies used in two previous meta-analyses (Bishop, 1990; Eglinton & Annett, 1994) as well as studies identified through PubMed MEDLINE, PsycInfo, Google Scholar, and Web of Science up to August 2022. K = 68 studies (n = 4660 individuals with dyslexia; n = 40845 controls) were entered into three random effects meta-analyses using the odds ratio as the effect size (non-right-handers; left-handers; mixed-handers vs. total). Evidence of elevated levels of atypical hand preference in dyslexia emerged that were especially pronounced for mixed-hand preference (OR = 1.57), although this category was underdefined. Differences in (direction or degree) of hand skill or degree of hand preference could not be assessed as no pertinent studies were located. Our findings allow for robust conclusions only for a relationship of mixed-hand preference with dyslexia.
近百年来，心理学家一直在研究手偏好与阅读障碍之间的联系。我们进行了一项荟萃分析，以确定阅读障碍中是否确实存在非典型手偏好的增加。我们纳入了之前两项荟萃分析（Bishop，1990；Eglinton 和 Annett，1994）中使用的研究，以及通过 PubMed MEDLINE、PsycInfo、Google Scholar 和 Web of Science 至 2022 年 8 月确定的研究。K = 68 项研究（n = 4660 名阅读障碍个体；n = 40845 名对照组）被纳入三个随机效应荟萃分析，使用比值比作为效应量（非右利手；左利手；混合利手与总）。阅读障碍中非典型手偏好程度升高的证据明显，混合手偏好尤其明显（OR = 1.57），尽管这一类别定义不明确。由于未找到相关研究，无法评估手技能（方向或程度）或手偏好程度的差异。我们的发现仅允许对混合手偏好与阅读障碍之间的关系得出可靠的结论。
