Text Neck and Its Association With Cardiac Autonomic Function, Smartphone Addiction, and Psychophysiological Status in Young Adults.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 The increasing use of mobile devices has led to a rise in forward head posture (FHP), or "text neck," contributing to health issues. Additionally, nomophobia, or the fear of being without a mobile phone, has emerged as a growing behavioral concern, particularly among younger users. Methods This cross-sectional study aimed to assess FHP and its association with cardiac autonomic function, smartphone addiction, nomophobia, ergonomic risk, and neck disability in 84 participants aged 19-45 years. FHP was evaluated via craniovertebral (CV) angle measurement and cardiac autonomic status through heart rate variability, alongside smartphone addiction and psychological distress. Results Heart rate variability (HRV) analyses revealed a significant inverse relationship between the CV angle and the LF/HF ratio, indicating heightened sympathetic activity with reduced CV angle. Parasympathetic indicators, root mean square of successive differences between adjacent NN intervals (RMSSD) and pNN50, positively correlated with CV angle, suggesting a link between optimal posture and enhanced parasympathetic function. Psychophysiological assessments showed that smartphone addiction moderately correlated with nomophobia. Conclusion Text neck or forward head posture is associated with increased sympathetic and decreased parasympathetic modulation, as evidenced by HRV indices.
