Interobserver Reliability in the Diagnosis of Pulpal and Periradicular Disease
The purpose of this study was evaluate the interobserver reliability of endodontists in the diagnosis the presence or absence of pulpal and/or periradicular disease. The study used 47 patients presenting to the VCU School of Dentistry for screening appointments as a test population under the rules …

Assessment of the interobserver and the intra observer reproducibility for the detection of renal cortical defects in adults and children using [99mtc]Tc-MAG3
… of [99mTc]Tc-MAG3 renography. We aim to assess interobserver and intraobserver reproducibility for detecting renal cortical defects using [ 99mTc]Tc-MAG3 for adults and children; identify causes for poor inter- and intraobserver reproducibility and to assess the effect of the kidney to …

Radiographic Union Score for Tibia (RUST) scoring system in adult diaphyseal femoral fractures treated with intramedullary nailing: an assessment of interobserver and intraobserver reliability
… scored by three reviewers using the RUST system. Interobserver reliability was measured at initial scoring. The 60 sets of radiographs were scored again by the three reviewers to calculate the intraobserver reliability. Results The RUST scores ranged from 4 to 12 with a mean score of 11.3 ± 1.3. …

Perspectives on the management of humerus fractures due to gunshot trauma: an inter- and intra-observer agreement and reliability study
… on gunshots of the humerus were available. Interobserver agreement studies reported low levels of intra- and inter-rater reliability (IRR) for the classification of proximal humerus fractures using Neer and AO/OTA classification. The complexity of the fractures, the inconsistency of …

Self-regulation to practice: Incorporating the strategy to an early childhood special education setting
… impact of the treatment package was studied. Interobserver agreement (IOA) was used to determine accuracy to self-identify behaviors. Results indicated a student increase in identifying undesired and desired behaviors, the percentage of desired behaviors displayed, and the accuracy with …
