Comparison of citing pattern of the Indian Journal of Gastroenterology (IJG) with that of three general gastroenterology journals included in the Science Citation Index (SCI).
Citations in articles published in the IJG in the year 1988 were analyzed; data for three control journals [American Journal of Gastroenterology (AJG), Hepatogastroenterology (HGE) and Italian Journal of Gastroenterology (ItJG)] were obtained from the SCI Journal Citation Reports for the year 1988.
Yearwise distribution of citations and citing half-life; aggregate of citation scores [percentage of citations from a journal ximpact factor (IF) of that journal] for five journals most frequently cited by each of the journals; and, proportion of citations from three most cited general medical journals and three most cited gastroenterology journals as ranked by IF.
Percentage of citations for all years from 1979 to 1988 in the IJG were lower than in the three control journals, and citing half-life longer (9.0 yr vs 6.0, 6.4, 6.9 yr for the three control journals). While aggregate citation score of IJG for the five journals most frequently cited in it was lower than that of two control journals (178.7 vs 205.4, 140.7 and 201.5 for AJG, HGE and ItJG respectively), total citations in the IJG from three most cited general medical journals (8.8 vs 9.4, 6.1 and 9.2 for AJG, HGE and ItJG respectively) and from three most cited gastroenterology journals (16.3 vs 16.0, 15.0 and 14.1 for AJG, HGE and ItJG respectively) were comparable with the control journals; this was related to lower number of citations from the journals with the highest IF in both general medicine and gastroenterology.
Citations in IJG were older than those in the three control journals and tended to be from journals with lower IF. To improve the citation pattern of the IJG, authors contributing to it need to keep up with recent literature in high quality journals and to cite more recent citations.
比较《印度胃肠病学杂志》（IJG）与《科学引文索引》（SCI）收录的三本普通胃肠病学杂志的引用模式。
分析1988年发表在IJG上的文章中的引用情况；三本对照杂志[《美国胃肠病学杂志》（AJG）、《胃肠肝病学》（HGE）和《意大利胃肠病学杂志》（ItJG）]的数据来自1988年的SCI期刊引证报告。
按年份分布的引用次数和引用半衰期；各杂志最常引用的五种杂志的引用分数总和[某杂志的引用百分比×该杂志的影响因子（IF）]；以及按IF排名的引用次数最多的三本普通医学杂志和三本胃肠病学杂志的引用比例。
1979年至1988年各年份IJG的引用百分比均低于三本对照杂志，且引用半衰期更长（三本对照杂志分别为6.0年、6.4年、6.9年，IJG为9.0年）。虽然IJG中最常被引用的五种杂志的引用分数总和低于两本对照杂志（AJG、HGE和ItJG的引用分数总和分别为205.4、140.7和201.5，IJG为178.7），但IJG中引用次数最多的三本普通医学杂志的总引用次数（AJG、HGE和ItJG分别为9.4、6.1和9.2，IJG为8.8）以及引用次数最多的三本胃肠病学杂志的总引用次数（AJG、HGE和ItJG分别为16.0、15.0和14.1，IJG为16.3）与对照杂志相当；这与普通医学和胃肠病学领域中IF最高的杂志的引用次数较少有关。
IJG中的引用比三本对照杂志中的引用更陈旧，且倾向于来自IF较低的杂志。为改善IJG的引用模式，为该杂志撰稿的作者需要跟上高质量杂志的最新文献，并引用更新的文献。
