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
purposeProlonged smartphone use is frequently associated with poor neck posture and the development of Text Neck Syndrome (TNS). This study aimed to compare manual dexterity between university students with and without TNS and to investigate its relationship with neck disability and smartphone use. We hypothesized that university students with TNS would demonstrate significantly lower manual dexterity compared to those without TNS.
methodsThis cross-sectional study included 280 university students from a public university. Manual dexterity was assessed using the Purdue Pegboard Test (PPT), while neck disability, smartphone addiction, and pain intensity were evaluated using the Neck Disability Index, Smartphone Addiction Scale-Short Version (SAS-SV), and Visual Analogue Scale (VAS), respectively. Group comparisons, correlation analyses, and multivariate regression were performed to examine the relationships between TNS and manual dexterity.
resultsParticipants with TNS demonstrated significantly higher neck disability scores compared to those without TNS (p<0.001). Significant impairments were observed only in non-dominant hand dexterity (p=0.025), whereas no significant differences were found in other dexterity parameters (p>0.05). Smartphone usage duration showed statistically significant weak negative correlations with manual dexterity parameters (p<0.05). After adjusting for age, sex, and smartphone usage duration, TNS was independently associated with reduced non-dominant hand dexterity (β=-0.138, p=0.020).
conclusionTNS is independently associated with non-dominant hand dexterity, particularly in non-dominant hand performance. Although the effect size was small (Cohen's d = 0.274), these findings provide preliminary evidence of an association between TNS and reduced non-dominant hand dexterity.
