The Effectiveness of Audio Recordings in Aiding Students' Recall of Biochemistry Concepts: A Quasi-Experimental Study.
Article in Cureus, 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
Introduction Engaging students in the study of biochemistry requires the use of innovative teaching and learning (TL) strategies. It is essential to capitalize on the current generation's growing use of microphones by offering audio recordings that address key biochemistry concepts. Allowing students to listen to the audio recordings during study sessions could enhance comprehension and memory. This study aimed to assess the efficacy of audio recordings as an additional TL tool to help students remember biochemistry concepts. Methods Two hundred and fifty first-year Bachelor of Medicine and Bachelor of Surgery (MBBS) students from the 2022-2023 cohort at a tertiary care teaching institution in Chennai, India, received an audio recording summarizing important aspects after a topic was covered in the classroom. A Google Form with five multiple-choice questions (MCQs) via Google Classroom (California, United States) and a shared WhatsApp group (California, United States) was used to evaluate the usefulness of these audio resources. Students were asked to rate how helpful they thought the audio recordings were for remembering biochemistry concepts on a five-point Likert scale. Results After listening to the audio recordings, more than 92% (230/250) of students answered the MCQs correctly, compared to 54% (135/250) of students before listening to the audio recordings. After listening to the audio recordings, the mean score on the subsequent MCQ test increased considerably to 17.64±2.02 (p<0.0001) from 8.16±3.08 before the intervention. Conclusion The results indicate that audio recordings are a useful and affordable way to improve understanding of biochemistry concepts. Student acceptance of this alternate TL approach is high, and it holds promise for future advancements in teaching methods.
