BACKGROUND: Self-management support (SMS) for patients with COPD can improve health-related quality of life (HRQOL). However, it remains unclear what SMS strategies are most effective. Using peer support to advance self-management is promising, as peer supporters possess credibility and can serve as role models. METHODS: We conducted a single-blinded RCT comparing the effectiveness of two strategies to support patients with COPD. The strategies were 'Health Care Professional (HCP)' and 'HCP Plus...

Abstract Objectives Lymphovascular space invasion (LVSI) is an independent risk factor for recurrence and poor survival in early-stage endometrioid endometrial cancer (EEC), but optimal adjuvant treatment is unknown. We aimed to compare the survival of women with early-stage EEC with LVSI treated postoperatively with observation (OBS), radiation (RAD, external beam and/or vaginal brachytherapy), or chemotherapy (CHEMO)+/−RAD. Methods This was a multi-institutional, retrospective cohort study of ...

AbstractWe performed an empirical study of the perceived quality of scientific graphics produced by beginning R users in two plotting systems: the base graphics package (“base R”) and the ggplot2 a...

The R programming language is built on an ecosystem of packages, some that allow analysts to accomplish the same tasks. For example, there are at least two clear workflows for creating data visualizations in R: using the base graphics package (referred to as "base R") and the ggplot2 add-on package based on the grammar of graphics. Here we perform an empirical study of the quality of scientific graphics produced by beginning R users. In our experiment, learners taking a data science course on th...

Objective To determine whether the rate of sentinel lymph node (SLN) dissections that do not yield a lymph node on pathological analysis (9empty packet dissection9) changes with increasing surgeon experience in the setting of patients undergoing minimally invasive hysterectomy and SLN mapping using indocyanine green dye for endometrial cancer. Methods All patients undergoing SLN mapping using indocyanine green dye at the time of minimally invasive hysterectomy for endometrial cancer or complex a...

Git and GitHub are common tools for keeping track of multiple versions of data analytic content, which allow for more than one person to simultaneously work on a project. GitHub Classroom aims to provide a way for students to work on and submit their assignments via Git and GitHub, giving teachers an opportunity to teach these version control tools as part of their course. In the Fall 2017 semester, we implemented GitHub Classroom in two educational settings--an introductory computational statis...

: Most researchers do not deliberately claim causal results in an observational study. But do we lead our readers to draw a causal conclusion unintentionally by explaining why significant correlations and relationships may exist? Here we perform a randomized controlled experiment in a massive open online course run in 2013 that teaches data analysis concepts to test the hypothesis that explaining an analysis will lead readers to interpret an inferential analysis as causal. We test this hypothesi...
