Data for: Oral versus Intravenous Antibiotics for Bone and Joint Infection – Randomised controlled trial
No full textThe management of complex orthopedic infections usually includes a prolonged course of intravenous antibiotic agents. The OVIVA study investigated whether oral antibiotic therapy is noninferior to intravenous antibiotic therapy for this indication.
We collected data on 1054 adults treated for bone of joint infection at 26 UK centres.
Participants were randomly assigned to receive either intravenous or oral antibiotics to complete the first 6 weeks of therapy.
The primary end point was definitive treatment failure within 1 year after randomisation. Additional data on clinical variables (including information on line complications, episodes of C-Diff), antibiotic use, clinical reviews, severe adverse events, inpatient admissions and patient reported outcomes (EQ-5D-3L and Oxford Hip Score/ Oxford Knee Score for participants with infections in their hips/ knees). </p
Replication Data for: Twenty-Seven Years of Clinical Surveillance of Severe Malaria in Kilifi County, Kenya
No full textThis dataset contains clinical data from 18,000 children with severe malaria admitted to Kilifi County Hospital, Kenya, during a 27-year period of reducing transmission. Data collection was done through continuous surveillance of hospital admissions is ongoing in KCH since May 1989 as a partnership between the Research Programme and Kilifi County Department of Health. The dataset also includes demographic characteristics and malaria control activities such as distributions of insecticide-treated bed nets. A more detailed description of the data collection methodology is included in the related publication. </p

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Interactions between age and ITN use determine the risk of febrile malaria in children
Get PDFBackground: Control measures which reduce individual exposure to malaria are expected to reduce disease, but also to eventually reduce immunity. Reassuringly, long term data following community wide ITN distribution show sustained benefits at a population level. However, the more common practice in Sub-Saharan Africa is to target ITN distribution on young children. There are few data on the long term outcomes of this practice.Methodology/Principal Findings: Episodes of febrile malaria were identified by active surveillance in 383 children over 18 months of follow up. In order to compare the short and long term outcomes of ITN use, we examined interactions between ITN use and age (12-42 months of age versus 42-80 months) in determining the risk of febrile malaria. ITN use and older age protected against the first or only episode of malaria (Hazard Ratio [HR] =0.33, 95%CI 0.17-0.65 and HR =0.30, 95%CI0.17-0.51, respectively). The interaction term between ITN use and older age was HR =2.91, 95%CI 1.02-8.3, p=0.045, indicating that ITNs did not protect older children. When multiple episodes were included in analysis, ITN use and older age were again protective against malaria episodes (Incident Rate Ratio [IRR] =0.43 95%CI 0.27-0.7) and IRR = 0.23, 95%CI 0.13-0.42, respectively) and the interaction term indicated that ITNs did not protect older children (IRR =2.71, 95%CI 1.3-5.7, p=0.008). Conclusions/Significance: These data on age interactions with ITN use suggest that larger scale studies on the long term individual outcomes should be undertaken if the policy of targeted ITN use for vulnerable groups is to continue. © 2009 Bejon et al
