The impact of algorithm-driven exposure to disease-related short videos on rehabilitation outcomes in lumbar disc herniation patients: content heterogeneity and psychological mediating mechanisms.

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
Background: Short videos have become a primary channel for Lumbar Disc Herniation (LDH) patients to obtain disease knowledge and rehabilitation guidance. Algorithm-driven personalized recommendations may expose patients to heterogeneous LDH-related content, affecting their health anxiety and rehabilitation trajectories. Objective: This study explored the impacts of LDH-related short video exposure duration and content types on health anxiety and lumbar functional rehabilitation in LDH patients, and verified the mediating role of health anxiety. Methods: A 6-month prospective cohort study enrolled 213 LDH outpatients from Luoyang Orthopedic-Traumatological Hospital (Jan-Apr 2025). Demographic, clinical and short video usage data were collected. Health anxiety (MCQ-HA) and lumbar function (JOA) were assessed at baseline and follow-up. Pearson correlation, multiple linear regression, subgroup analysis and Bootstrap mediation analysis (5,000 resamplings) were used. Results: At 6-month follow-up, the mean JOA score decreased from 23.00 ± 1.59 at baseline to 21.96 ± 3.03, and the mean MCQ-HA score increased from 20.77 ± 4.57-21.86 ± 6.14. Pearson correlation analysis showed that daily viewing duration and exposure frequency to awareness-motivation content were significantly negatively correlated with Conclusion: Prolonged short video exposure and frequent awareness-motivation content viewing were associated with poorer rehabilitation and higher health anxiety, with health anxiety partially mediating these relationships, providing empirical evidence for digital health guidance.
