Historical Measurement Information Can Be Used to Improve Estimation of Structural Parameters in Structural Equation Models With Small Samples.
Article in Educational and psychological measurement, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study investigates the incorporation of historical measurement information into structural equation models (SEM) with small samples to enhance the estimation of structural parameters. Given the availability of published factor analysis results with loading estimates and standard errors for popular scales, researchers may use this historical information as informative priors in Bayesian SEM (BSEM). We focus on estimating the correlation between two constructs using BSEM after generating data with significant bias in the Pearson correlation of their sum scores due to measurement error. Our findings indicate that incorporating historical information on measurement parameters as priors can improve the accuracy of correlation estimates, mainly when the true correlation is small-a common scenario in psychological research. Priors derived from meta-analytic estimates were especially effective, providing high accuracy and acceptable coverage. However, when the true correlation is large, weakly informative priors on all parameters yield the best results. These results suggest leveraging historical measurement information in BSEM can enhance structural parameter estimation.
