From Development to Validation: Exploring the Efficiency of Numetrive, a Computerized Adaptive Assessment of Numerical Reasoning.

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
The goal of the present study is to describe the methods used to assess the effectiveness and psychometric properties of Numetrive, a newly developed computerized adaptive testing system that measures numerical reasoning. For this purpose, an item bank was developed consisting of 174 items concurrently equated and calibrated using the two-parameter logistic model (2PLM), with item difficulties ranging between -3.4 and 2.7 and discriminations spanning from 0.51 up to 1.6. Numetrive constitutes an algorithmic combination that includes maximum likelihood estimation with fences (MLEF) for
