A Four-Step Micro-Research Closed-Loop Model via Online Spreadsheets for Molecular Biology Experimental Teaching: A Polymerase Chain Reaction (PCR) Case Study.

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
Objectives: To develop and evaluate a low-cost, 4-step micro-research closed-loop teaching model using Tencent Docs spreadsheets to improve polymerase chain reaction (PCR) experimental teaching in a sophomore molecular biology course. Methods: In a single-institution, nonrandomized quasi-experimental study, 33 students from Capital Medical University were assigned to either an experimental group ( Results: The experimental group completed protocol design more quickly (8.04 ± 0.81 vs 12.58 ± 1.08 min; Conclusion: In this small, nonrandomized cohort, use of an online spreadsheet-based micro-research closed-loop model was associated with shorter protocol design time, fewer low-level errors, higher experimental confidence, and larger short-term improvements in PCR theoretical knowledge. These preliminary findings suggest that a lightweight, readily scalable "digital laboratory" may help support PCR experimental teaching in resource-constrained settings, although more rigorous, larger-scale studies with long-term and higher-order learning outcomes are needed before drawing firm causal conclusions.
