- Psychology, MedicineBMC Medical Research Methodology
Reporting quality of systematic review abstracts in the field of anesthesiology is suboptimal, and did not improve after publication of PRISMA-A checklist in 2013, and need stricter adherence to reporting checklists by authors, editors and peer-reviewers.

Bias in meta-analysis detected by a simple, graphical test
Funnel plots, plots of the trials' effect estimates against sample size, are skewed and asymmetrical in the presence of publication bias and other biases Funnel plot asymmetry, measured by regression analysis, predicts discordance of results when meta-analyses are compared with single large trials.

A comparison of statistical methods for meta‐analysis

It is shown that the commonly used DerSimonian and Laird method does not adequately reflect the error associated with parameter estimation, especially when the number of studies is small, and three methods currently used for estimation within the framework of a random effects model are considered.
Operating characteristics of a rank correlation test for publication bias.
An adjusted rank correlation test is proposed as a technique for identifying publication bias in a meta-analysis, and its operating characteristics are evaluated via simulations. The test statistic…
Impact of allocation concealment on conclusions drawn from meta-analyses of randomized trials.
- MedicineInternational journal of epidemiology
Two-thirds of conclusions in favour of one of the interventions were no longer supported if only trials with adequate allocation concealment were included, and the loss of support mainly reflected loss of power and a shift in the point estimate towards a less beneficial effect.
