2018 Database of Effect Sizes (ES)
收藏资源简介：
The database contains 18 fields:- xmlfile: identification of the xmlfile from which the ES was extracted.- id: a unique identifier of extracted ES within a given xmlfile.- pmid: the PMID identifier of the abstract from which ES were extracted. - year: year of publication of the abstract.- month: month of publication of the abstract.- or: value of the ES (T#0).- lci: value of the lower part of the confidence interval.- hci: value of the higher part of the confidence interval.- orhrrr: classification of the type of ES (OR, HR, RR and PR). PR was considered as OR at the step of the statistical script.- ci: type of confidence interval (90%, 95% or 99%). If no CI was provided, 95% was assumed at the step of the statistical script.- counteies: continents extracted from author’s affiliations, using MapAfill and text mining (pipe ‘|’ delimited)- adjusted: 1 if an adjusted ES was detected (e.g. adjusted OR, aOR), 0 otherwise.- multivariate: 1 if a multivariate analysis was found within abstract, 0 otherwise.- sr: 1 if the abstract was a “Review” (review, systematic review or meta-analysis), 0 otherwise.- ccj: 1 if the journal was found within the Core Clinical Journals list, 0 otherwise.- doaj: 1 if the journal was found within the Directory of Open Access Journals, 0 otherwise. - pmc: PubMed Central identifier, if exists.- nlm: unique identifier of the journal abstract.
本数据库共包含18个字段，各字段说明如下： 1. xmlfile：提取该效应量（Effect Size, ES）所源自的XML文件的标识； 2. id：单个XML文件内，所提取的ES的唯一标识符； 3. pmid：提取ES所源自的摘要的PubMed文献识别号（PMID）； 4. year：该摘要的发表年份； 5. month：该摘要的发表月份； 6. or：效应量的取值（T#0）； 7. lci：置信区间下限的取值； 8. hci：置信区间上限的取值； 9. orhrrr：ES类型的分类（包括比值比（Odds Ratio, OR）、风险比（Hazard Ratio, HR）、相对危险度（Relative Risk, RR）以及预后比（Prognostic Ratio, PR）），在统计脚本处理步骤中，PR被视作OR； 10. ci：置信区间的类型（90%、95%或99%）。若未提供置信区间，则在统计脚本处理步骤中默认采用95%置信区间； 11. counteies：通过MapAfill工具与文本挖掘从作者所属机构中提取的大洲信息，以竖线‘|’作为分隔符； 12. adjusted：若检测到经校正的ES（如校正比值比（adjusted Odds Ratio, aOR）），则取值为1，否则为0； 13. multivariate：若摘要中提及多变量分析，则取值为1，否则为0； 14. sr：若该摘要为综述类文献（包括综述、系统综述或元分析），则取值为1，否则为0； 15. ccj：若该期刊收录于核心临床期刊（Core Clinical Journals）列表中，则取值为1，否则为0； 16. doaj：若该期刊收录于开放获取期刊目录（Directory of Open Access Journals, DOAJ）中，则取值为1，否则为0； 17. pmc：PubMed Central（PMC）标识符，若存在则填写； 18. nlm：期刊摘要的唯一标识符。
