The purpose of this study was to survey the growth of Google Scholar public profiles in orthopedics over a 12-month period and to investigate global patterns.
Data was prospectively acquired from June 2013 to June 2014. Google Scholar queries specific to orthopedic surgery were performed at 90-day intervals. Demographic aspects of each user were also compiled, including gender, current location, and primary interests. To determine differences between the growth of Google Scholar public profile registrations and citation counts, as well as differences in growth in different regions, repeated measures of analysis of variance (RMANOVA) were used.
RMANOVA revealed statistically significant differences ( p = 0.0001) for regional growth. The largest growth was observed in the United Kingdom ( p = 0.009, 289%), followed by the Asia-Pacific region ( p = 0.004, 177%) and "Other" ( p = 0.006, 172%). The mean growth per 90-day interval is 19.9% ( p = 0.003) and the mean 12-month growth is 107% ( p = 0.05). Statistically significant differences between gender (male vs. female) and basic and clinical sciences ( χ = 22.4, p = 0.0001) were observed.
This study suggests an exponential growth in the number of authors in the field of orthopedic surgery creating a Google Scholar public profile, and at the current rate participation doubles every 10.6 months.
本研究的目的是调查12个月内骨科领域谷歌学术公开资料的增长情况，并研究全球模式。
前瞻性收集2013年6月至2014年6月的数据。每隔90天进行一次针对骨外科的谷歌学术查询。还收集了每个用户的人口统计学信息，包括性别、当前位置和主要兴趣。为了确定谷歌学术公开资料注册增长与引用次数之间的差异，以及不同地区增长的差异，使用了重复测量方差分析（RMANOVA）。
RMANOVA显示区域增长存在统计学显著差异（p = 0.0001）。英国增长幅度最大（p = 0.009，289%），其次是亚太地区（p = 0.004，177%）和“其他”地区（p = 0.006，172%）。每90天间隔的平均增长率为19.9%（p = 0.003），12个月的平均增长率为107%（p = 0.05）。观察到性别（男性与女性）以及基础科学与临床科学之间存在统计学显著差异（χ = 22.4，p = 0.0001）。
本研究表明，创建谷歌学术公开资料的骨外科领域作者数量呈指数增长，按照当前速度，参与人数每10.6个月翻一番。
