TLDR
Alternatives include presenting results in the units of the most popular or interpretable measure, converting to dichotomous measures and presenting relative and absolute effects, presenting the ratio of the means of intervention and control groups, and presenting the results in minimally important difference units.About:

Surgical portosystemic shunts versus transjugular intrahepatic portosystemic shunt for variceal haemorrhage in people with cirrhosis
TL;DR: Evidence appears to suggest improved health-related quality of life in people who received surgical shunt compared with TIPS, and the certainty of the evidence for all-cause mortality at 30 days and five years, irreversible shunt occlusion, and encephalopathy is downgraded.
Journal ArticleDOI
Simultaneous synthesis of treatment effects and mapping to a common scale: an alternative to standardisation
TL;DR: In this paper, the authors explored a method for synthesizing treatment effect information both within and between trials and for reporting treatment effects on a common scale as an alternative to standardisation study design.
Journal ArticleDOI
Virtual and augmented reality in the vestibular rehabilitation of peripheral vestibular disorders: systematic review and meta-analysis.
TL;DR: In this paper, evidence of the efficacy of VR and AR delivered rehabilitation in patients with peripheral vestibular disorders is reviewed, and five studies meeting eligibility criteria were included, including four studies with bias assessment and meta analyses were planned.
Journal ArticleDOI
Effect of tree nuts on glycemic outcomes in adults with type 2 diabetes mellitus: a systematic review.
TL;DR: Pistachio consumption for three months or less significantly reduced triglyceride levels, and other tree nuts (walnuts, almonds, and hazelnuts) reduced fasting blood glucose and glycated hemoglobin levels by varying degrees.
Journal ArticleDOI
A Call for Evidence-based Decision Making When Selecting Outcome Measurement Instruments for Summary of Findings Tables in Systematic Reviews: Results from an OMERACT Working Group.
Dorcas E. Beaton,Caroline B. Terwee,Jasvinder A. Singh,Gillian A. Hawker,Donald L. Patrick,Laurie B. Burke,Karine Toupin-April,Peter Tugwell +7 more
TL;DR: An approach blending 2 initiatives: OMERACT and COSMIN is explored, which led to an evidence-based approach that depended both on a clear definition of target concept and a review of measurement performance of the instrument.

Statistical Power Analysis for the Behavioral Sciences
TL;DR: The concepts of power analysis are discussed in this paper, where Chi-square Tests for Goodness of Fit and Contingency Tables, t-Test for Means, and Sign Test are used.
Journal ArticleDOI
Development of a Rating Scale for Primary Depressive Illness
TL;DR: This is an account of further work on a rating scale for depressive states, including a detailed discussion on the general problems of comparing successive samples from a ‘population’, the meaning of factor scores, and the other results obtained.

GRADE guidelines: 1. Introduction-GRADE evidence profiles and summary of findings tables

TL;DR: The GRADE process begins with asking an explicit question, including specification of all important outcomes, and provides explicit criteria for rating the quality of evidence that include study design, risk of bias, imprecision, inconsistency, indirectness, and magnitude of effect.

TL;DR: The approach of GRADE to rating quality of evidence specifies four categories-high, moderate, low, and very low-that are applied to a body of evidence, not to individual studies.
