OBJECTIVE To determine intra and interobserver agreement of the grading system for femoral cementation in hip arthroplasty proposed by Barrack. METHODS Immediate anteroposterior and lateral postoperative radiographs of 55 primary total hip arthroplasties were assessed by two observers familiar with the use of this grading system. The assessments were performed on two separate occasions by eac...

Although the third heart sound (S3) is well recognized as an important sign in the evaluation of patients with congestive heart failure, the interobserver variability with its observation needs to be known before general applicability can be determined. Therefore, we determined the agreement among four trained observers on the presence of S3 in 81 hospitalized patients. Agreement between pairs ...

OBJECTIVE To study interobserver agreement in the assessment of intrapartum automated fetal electrocardiogram ST interval analysis (STAN). DESIGN Observational study. SETTING Labor ward in tertiary level university hospital. Sample. Two hundred (140 reassuring and 60 non-reassuring) STAN recordings on non-selected women with singleton, vertex, term pregnancies were selected from our archive...

BACKGROUND Fractures of the proximal radius need to be classified in an appropriate and reproducible manner. The aim of this study was to assess the reliability of the three most widely used classification systems. METHODS Elbow radiographs images of patients with proximal radius fractures were classified according to Mason, Morrey, and Arbeitsgemeinschaft für osteosynthesefragen/Association ...

BACKGROUND Immunohistochemical (IHC) assessment of estrogen receptor (ER) and progesterone receptor (PR) status has become a routine practice to predict the likely outcome of Tamoxifen therapy. AIMS To assess the interobserver variation in scoring hormone receptor status of breast carcinoma, using the Quick Score. MATERIALS AND METHODS IHC-stained slides of breast carcinomas reported by the...

OBJECTIVE To measure agreement between nine structured approaches for diagnosing childhood tuberculosis; to quantify differences in the number of tuberculosis cases diagnosed with the different approaches, and to determine the distribution of cases in different categories of diagnostic certainty. METHODS We investigated 1445 children aged < 2 years during a vaccine trial (2001-2006) in a rura...

BACKGROUND Lymphovascular invasion (LVI) in colorectal cancer (CRC) is considered a strong stage-independent prognostic factor and influences decisions regarding adjuvant chemotherapy in patients with stage II tumors. However, the degree of interobserver agreement among pathologists for LVI in CRC is largely unknown. This study was undertaken to examine such interobserver variability, and we hy...

BACKGROUND Multiple studies suggest that reduced postural orientation is a possible risk factor for both patello-femoral joint pain (PFP) and rupture of the anterior cruciate ligament (ACL). In order to prevent PFP and ACL injuries in adolescent athletes, it is necessary to develop simple and predictive screening tests to identify those at high risk. Single Leg Mini Squat (SLMS) is a functional...

With the massive outbreak of coronavirus (COVID-19) disease, demand for automatic and quick detection COVID-19 has become a crucial challenge scientists around world. Many researchers are working on finding an automated effective system detecting COVID-19. They have found that computed tomography (CT-scan) X-ray images infected patients can provide more accurate faster results. In this paper, i...
