    Il mal di schiena (Low-Back Pain, LBP) ha rice- vuto crescente attenzione, divenendo una delle principali cause di morbosità, assenza dal lavoro e spesa sanita- ria. Data la rilevanza clinica, epidemiologica ed economica del problema, numerose linee guida (LG) sono state ela- borate a livello internazionale negli ultimi anni, allo scopo di sistematizzare e razionalizzare l’approccio diagnosti- co e terapeutico al problema. Per questo motivo, nell’ambito della convenzione SIOT- ISS, si è scelto di produrre un documento di sintesi rapida della letteratura sul mal di schiena sul modello delle Ban- che Dati Comparative (Box 1: Banca dati comparativa di LG), che costituirà la base di partenza per i futuri docu- menti SNLG sull’argomento

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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
