Treatment Effects in Pharmacological Clinical Randomized Controlled Trials are Mainly Due to Placebo.

Objectives: The placebo response in clinical trials has four components: regression to the mean (RTM), measurement artefacts, natural tendency (NT) of the disease, and the genuine placebo effect. Our objective is to determine what contributes to the size of the placebo-effect in clinical trials by meta-regressions of randomized placebo-controlled clinical trials.

Study Design And Setting: We identified five diseases where data on the rates of NT were available to search for a sample of n=150 (5x30) RCTs.

Non-surgical treatment of residual periodontal pockets using sodium hypochlorite/amino acid gel and cross-linked hyaluronic acid-a 9-month pilot randomized controlled clinical trial.

Objectives: This pilot randomized controlled clinical trial compares the clinical outcome obtained in persistent periodontal pockets during 9-month follow-up of supportive periodontal step 4 treatment performed by either combining subgingival instrumentation with adjunctively used sodium hypochlorite/amino acid gel and crosslinked hyaluronic acid (xHyA) or subgingival instrumentation alone.

Materials And Methods: Study protocol is registered under NCT06438354 at Clinicaltrials.gov.

Digital Drawing Tools for Assessing Mental Health Conditions - A Scoping Review.

Introduction: Drawing tasks are an elementary component of psychological assessment in the evaluation of mental health. With the rise of digitalization not only in psychology but healthcare in general, digital drawing tools (dDTs) have also been developed for this purpose. This scoping review aims at summarizing the state of the art of dDTs available to assess mental health conditions in people above preschool age.
