We propose an approach for constructing and evaluating the performance of inverse probability weighted robust mixture priors (IPW-RMP) which are applied to the parameters in treatment group-specific marginal models.

The effect of periodontal treatment on the connective tissue fibers of the marginal gingiva: II
The Journal of the American Dental Association, 1954Tests with disclosing solution and repeated biopsies of the marginal gingiva after periodontal treatment show the positive effects of therapeutic measures. Home care included the daily use of soft bristle toothbrushes, unwaxed dental floss and a water spray.

Crossover can bias clinical outcomes of randomized clinical trials by increasing the risk of both type I (false positive) and type II (false negative) errors. To show how crossover can increase type I error, we provide computer simulation and review herein illustrative examples (iniparib, olaratumab) of recently reported RCTs that demonstrated false ...

Estimating marginal treatment effects in heterogeneous populations [PDF]
Annals of Economics and Statistics, 2007 This paper proposes a nonparametric method of estimating marginal treatment effects in heterogeneous populations. Building upon an insight of Heckman and Vytlacil, the conventional treatment effects model with heterogeneous effects is shown to imply that outcomes are a nonlinear function of participation probabilities.

When making causal inferences, treatment‐induced confounders complicate analyses of time‐varying treatment effects. Conditioning on these variables naively to estimate marginal effects may inappropriately block causal pathways and may induce spurious ...

Effect of post-implant edema on prostate brachytherapy treatment margins
International Journal of Radiation Oncology*Biology*Physics, 2005To determine if postimplant prostate brachytherapy treatment margins calculated on Day 0 differ substantially from those calculated on Day 30.Thirty patients with 1997 American Joint Commission on Cancer clinical stage T1-T2 prostatic carcinoma underwent prostate brachytherapy with I-125 prescribed to 144 Gy.

Effect of respiratory trace shape on optimal treatment margin.
Medical physics, 2011To evaluate the effect of target trajectory shape on the optimal treatment margin.Intensity-modulated radiation therapy and volumetric modulated arc therapy plans were created for three spherical targets (3, 5, and 7 cm diameter) simulated in exhalation phases, each with margins of 2, 4, 6, 8, and 10 mm to account for motion.

Corneal Cross-Linking: An Effective Treatment Option for Pellucid Marginal Degeneration
Seminars in Ophthalmology, 2019Purpose: This is the first review article examining literature specific to the use of corneal cross-linking (CXL) to treat pellucid marginal degeneration (PMD). Results: CXL appears to be an effective treatment that may halt the progression of PMD to stabilize vision.

The objective of this study was to compare the effect of a monitored chlorhexidine (CHX) gel treatment with a conventional two-day CHX treatment in subjects with well-restored dentitions and high numbers of salivary mutans streptococci (MS).In the test group (n = 8), the effect of the CHX gel applications was monitored in margins of restorations and in
