Bias in meta-analysis detected by a simple, graphical test
TL;DR: 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.

Measuring agreement in method comparison studies
J M Bland,Douglas G. Altman +1 more
TL;DR: The 95% limits of agreement, estimated by mean difference 1.96 standard deviation of the differences, provide an interval within which 95% of differences between measurements by the two methods are expected to lie.

Caroline B. Terwee,Sandra D.M. Bot,Michael R. de Boer,Daniëlle A W M van der Windt,Dirk L. Knol,Joost Dekker,Lex M. Bouter,Henrica C.W. de Vet +7 more
TL;DR: The criteria can be used in systematic reviews of health status questionnaires, to detect shortcomings and gaps in knowledge of measurement properties, and to design validation studies.

TL;DR: This paper shall describe what is usually done, show why this is inappropriate, suggest a better approach, and ask why such studies are done so badly.

Relation between initial blood pressure and its fall with treatment.
TL;DR: Positive correlations between pre-treatment blood-pressure and the fall in pressure after treatment was examined for most classes of antihypertensive drugs and suggests that for all manoeuvres response is related to the height of the pretreatment pressure.

TL;DR: This method was used to compare observed numbers of deaths from five types of leukaemia with their respective "expected" numbers but seven deaths is far too few for such tests.
