Background: Progression-free survival is an increasingly popular surrogate endpoint for overall survival. The strength of correlation between the two endpoints varies, raising questions about the correlation between results of interim analyses that report mature progression-free survival data with the subsequent final publication that report overall survival. Methods: We searched PubMed from 2005 to 2015 for randomized controlled trials that measured both progression-free survival and overall survival...

The starting point of this paper is a desktop research assessment model that does not take properly into account the complexities of research assessment, but rather bases itself on a series of highly simplifying, questionable assumptions related to the availability, validity and evaluative significance of research performance indicators, and to funding policy criteria. The paper presents a critique of this model, and proposes alternative assessment approaches, based on an explicit evaluative framework, focusing on preconditions to performance or communication effectiveness rather than on performance itself, combining metrics and expert knowledge and using metrics primarily to set minimum standards...

Altmetric indicators are increasingly present in the research landscape. Among this ecosystem of heterogeneous indicators, social reference managers have been proposed as indicators of broader use of scholarly work. However, little work has been done to understand the data underlying this indicator. The present work uses a large-scale survey to study the users of two prominent social reference managers-Mendeley and Zotero. The survey examines demographic characteristics, usage of the platforms, as well as attitudes towards key issues in scholarly communication, such as open access, peer review, privacy, and the reward system of science...

INTRODUCTION: Researchers, funders, and institutions are interested in understanding and quantifying research dissemination and impact, particularly related to communicating with the public. Traditionally, citations have been a primary impact measure; however, citations can be slow to accrue and focus on academic use. Recently altmetrics, which track alternate dissemination forms (e. g., social media), have been suggested as a complement to citation-based metrics. This study examines the relationship between altmetrics and traditional measures: journal article citations and access counts...

Importance: Clinical colorectal cancer registries (CCCRs) are potentially powerful tools in colorectal cancer research. They are resource intensive, but to our knowledge, no formal review of their value exists. While quality control, clinical audit, and benchmarking are important factors in assessing the value of maintaining CCCRs, they are difficult to quantify. This study focuses on registry research output as a measure of value; the study hypothesizes that CCCRs do not produce sufficient published research output of clinical significance to justify the resources required to maintain them...

Lutz Bornmann, Robin Haunschild
In this study, we address the question whether (and to what extent, respectively) altmetrics are related to the scientific quality of papers (as measured by peer assessments). Only a few studies have previously investigated the relationship between altmetrics and assessments by peers. In the first step, we analyse the underlying dimensions of measurement for traditional metrics (citation counts) and altmetrics-by using principal component analysis (PCA) and factor analysis (FA). In the second step, we test the relationship between the dimensions and quality of papers (as measured by the post-publication peer-review system of F1000Prime assessments)-using regression analysis...

The data collection and reporting approaches of four major altmetric data aggregators are studied. The main aim of this study is to understand how differences in social media tracking and data collection methodologies can have effects on the analytical use of altmetric data. For this purpose, discrepancies in the metrics across aggregators have been studied in order to understand how the methodological choices adopted by these aggregators can explain the discrepancies found. Our results show that different forms of accessing the data from diverse social media platforms, together with different approaches of collecting, processing, summarizing, and updating social media metrics cause substantial differences in the data and metrics offered by these aggregators...

Science communication is seen as critical for the disciplines of ecology and conservation, where research products are often used to shape policy and decision making. Scientists are increasing their online media communication, via social media and news. Such media engagement has been thought to influence or predict traditional metrics of scholarship, such as citation rates. Here, we measure the association between citation rates and the Altmetric Attention Score-an indicator of the amount and reach of the attention an article has received-along with other forms of bibliometric performance (year published, journal impact factor, and article type)...

BACKGROUND: There is interest from authors and publishers in sharing the results of their studies over the Internet in order to increase their readership. In this way, articles tend to be discussed and the impact of these articles tends to be increased. In order to measure this type of impact, a new score (named Altmetric) was created. Altmetric aims to understand the individual impact of each article through the attention attracted online. OBJECTIVE: The primary objective of this study was to analyze potential factors related with the publishing journal and the publishing trial that could be associated with Altmetric scores on a random sample of low back pain randomized controlled trials (RCTs)...
