Indian Journal of Palliative Care (IJPC) provides a comprehensive multidisciplinary evidence base for an evidence-informed clinical decision making.
To analyze the levels of evidence of articles published in IJPC in the years 2010-2011.
Systematic review of palliative care journals.
Systematic review of articles was done and was scored according to Center for Evidence-Based Medicine levels of evidence into any of the five grades. The articles were categorized based upon article type, number of authors, study approach, age focus, population focus, disease focus, goals of care, domains of care, models of care, and year of publication.
All descriptive analysis was done using frequencies and percentiles, and association between all categorical variables was done using Chi-square test at 95% confidence interval (CI) using Statistical Package for Social Sciences (SPSS) version 16 for Windows (SPSS Inc, Chicago, IL).
There was a greater prevalence of low level evidence (level 4: n = 46, 51%; level 5: n = 35, 39%) among the 90 selected articles, and article type (original articles with higher level of evidence, P = 0.000), article approach (analytical studies with higher level of evidence, P = 0.000), domains of palliative care (practice-related studies with higher level of evidence, P = 0.000) and models of care (biological or psychosocial model with higher level of evidence, P = 0.044) had a significant association with the grade of levels of evidence. Association with other factors was not statistically significant (P < 0.05).
The levels of research evidence for palliative care provided by articles published in IJPC were predominantly level 4 and level 5, and there is scope for more high quality evidence to inform palliative care decisions in the developing countries.
《印度姑息治疗杂志》（IJPC）为循证临床决策提供了全面的多学科证据基础。
分析2010 - 2011年发表在IJPC上的文章的证据水平。
对姑息治疗期刊进行系统评价。
对文章进行系统评价，并根据循证医学中心的证据水平分为五个等级中的任意一级进行评分。文章根据文章类型、作者数量、研究方法、年龄关注点、人群关注点、疾病关注点、护理目标、护理领域、护理模式和发表年份进行分类。
所有描述性分析使用频率和百分位数进行，所有分类变量之间的关联使用社会科学统计软件包（SPSS）Windows版16（SPSS公司，伊利诺伊州芝加哥）在95%置信区间（CI）下进行卡方检验。
在90篇入选文章中，低水平证据（4级：n = 46，51%；5级：n = 35，39%）的比例更高，文章类型（证据水平较高的原创文章，P = 0.000）、文章方法（证据水平较高的分析性研究，P = 0.000）、姑息治疗领域（证据水平较高的实践相关研究，P = 0.000）和护理模式（证据水平较高的生物或心理社会模式，P = 0.044）与证据水平等级有显著关联。与其他因素的关联无统计学意义（P < 0.05）。
IJPC上发表的文章所提供的姑息治疗研究证据水平主要为4级和5级，在发展中国家，仍有空间提供更多高质量证据以指导姑息治疗决策。
