In the health sciences it is quite common to carry out studies designed to determine the influence of one or more variables upon a given response variable. When this response variable is numerical, simple or multiple regression techniques are used, depending on the case. If the response variable is a qualitative variable (dichotomic or polychotomic), as for(More)
OBJECTIVES Immediate post-mastectomy breast reconstruction (IBR) is a procedure that has proven advantages, but it also entails risks. The aim of this study was to identify risk factors for reconstruction failure. METHODS A review was made of all the IBR carried out at a general hospital from 2002 to 2009. Retrospective information was obtained about(More)
OBJECTIVE To study the concordance of the radiographic classification of Eaton-Littler for the diagnosis of basal thumb joint osteoarthritis (BTJO). The null hypothesis was that the concordance was due to chance and the alternative was that the concordance was not due to chance. MATERIAL AND METHOD We have observed the x-rays of 46 patients with symptoms(More)
OBJECTIVE To compare the effectiveness of additional moxibustion at point BL67 with moxibustion at a non-specific acupuncture point and with usual care alone to correct non-vertex presentation. METHODS This was a multicentre randomised controlled trial in which 406 low-risk pregnant women with a fetus in ultrasound breech presentation, with a gestational(More)
The purpose of this study was to compare outcomes of hip fractures treated by orthopaedic surgeons, performed by specialist vs. non-specialist surgeons. The rate of surgical site infection (SSI) obtained is taken as the main variable. This was a prospective controlled cohort study of 814 patients presenting with hip fractures, operated on by a group of(More)
BACKGROUND Obstetric epidural analgesia (EA) is widely applied, but studies have reported that its use may be less extensive among immigrant women or those from minority ethnic groups. Our aim was to examine whether this was the case in our geographic area, which contains an important immigrant population, and if so, to describe the different components of(More)
Reviews of the efficacy of acupuncture as a treatment for acute low back pain have concluded that there is insufficient evidence for its efficacy and that more research is needed to evaluate it. A multicentre randomized controlled trial was conducted at 4 primary-care centres in Spain to evaluate the effects of acupuncture in patients with acute nonspecific(More)
The association between mental disorders (MDs) and iatrogenic complications after hip fracture surgery has been poorly studied. Among iatrogenic complications, nosocomial infections (NIs) are a major factor in hip fracture surgery. The aim of this paper was to determine whether patients with a MD and a hip fracture develop more NIs after hip surgery than(More)
Surgery for the treatment of hip fractures is considered the gold standard even among nonagerians with a heavy comorbidity burden. Therefore, a study of an association between surgical complications and some variables in elderly individuals appears to be very important. We designed a transverse study in which we determined patient age at the time of(More)
INTRODUCTION Unreamed intramedullary nailing (UIMN) is an effective treatment procedure for the majority of tibial fractures, with locking constituting the technical support for the buttressing and neutralisation principles underlying intramedullary nailing. It has been claimed that the added versatility obtained from the use of more bolts in distal locking(More)
