Correlation and agreement are 2 concepts that are widely applied in the medical literature and clinical practice to assess for the presence and strength of an association. However, because correlation and agreement are conceptually distinct, they require the use of different statistics. Agreement is a concept that is closely related to but fundamentally different from and often confused with correlation. ⋯ Questionnaires, psychometric scales, and diagnostic tests are widespread and increasingly used by not only researchers but also clinicians in their daily practice. It is essential that these questionnaires, scales, and diagnostic tests have a high degree of agreement between observers. It is therefore vital that biomedical researchers and clinicians apply the appropriate statistical measures of agreement to assess the reproducibility and quality of these measurement instruments and decision-making processes.

Academic Anesthesiology Career Development: A Mixed-Methods Evaluation of the Role of Foundation for Anesthesiology Education and Research Funding.
In 1986, the American Society of Anesthesiologists created the Foundation for Anesthesiology Education and Research (FAER) to fund young anesthesiology investigators toward the goal of helping launch their academic careers. Determining the impact of the FAER grant program has been of importance. ⋯ This cross-sectional data demonstrated career success in publications, grants, and leadership positions for faculty who apply for a FAER grant. A FAER grant application may be a marker for an anesthesiologist who is interested in pursuing a physician-scientist career.

Effect of Beam Steering on Echogenic and Nonechogenic Needle Visibility at 40°, 50°, and 60° Needle Insertion Angles.
Currently, there is little understanding of the role of echogenic needles and beam steering at moderate angles of needle insertion. The ultrasound images of the echogenic and nonechogenic needles inserted into pork at 40°, 50°, and 60° were scored by anesthesiologists on a scale of 0-10. ⋯ At 40°, steep beam steering improves visualization of both nonechogenic and echogenic needles to an equal, satisfactory level. At 50° and 60°, visualization of nonechogenic needles is poor, whereas visibility of an echogenic needle was adequate and may be improved with steep beam steering.
