Introducing Experimental Design Concepts Improves Biochemistry Undergraduates' Experimental Laboratory Competence and Confidence.
Article in Biochemistry and molecular biology education : a bimonthly publication of the International Union of Biochemistry and Molecular Biology. 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
Laboratory science education can provide a training ground for developing experimental design capabilities, the ability to critically assess a range of laboratory methods, and confidence in selecting, adapting, and performing laboratory techniques. However, traditional, fail-safe, protocol-based laboratories provide little opportunity for students to develop these cognitive abilities. We introduced experimental design elements into a second-year undergraduate biochemistry laboratory. Using a guided inquiry model, we show that students improve their self-perceived and externally measured ability to critically assess laboratory methods, design experiments, and adapt protocols (experimental laboratory competence) and gain confidence in adapting protocols and applying technical laboratory knowledge to new situations (experimental laboratory confidence). Furthermore, students on the whole reported enjoying engaging with experimental design.
