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: Smartphone addiction is an emerging public health concern, particularly among caregivers experiencing chronic stress. Caregivers of children with physical disabilities may be especially vulnerable, yet research on this topic in low-resource settings like Nepal is scarce. This study aimed to determine the prevalence of smartphone addiction and identify its sociodemographic, psychological, and social determinants among caregivers of children with physical disabilities. Methods: A quantitative, cross-sectional, descriptive study was conducted at the country's only specialized pediatric rehabilitation center in Nepal, a national referral hub providing comprehensive care for children with physical disabilities. Consecutive sampling was used to recruit 227 primary caregivers. Inclusion criteria were: age ≥18 years, primary responsibility for the child's daily care, and ability to complete a structured questionnaire. Exclusion criteria included caregivers with severe cognitive impairments or acute illness preventing participation. Data were collected using a structured questionnaire incorporating the Smartphone Addiction Scale-Short Version (SAS-SV). Descriptive statistics, Chi-square tests, t-tests, and multivariable logistic regression were used to examine associations between smartphone addiction and participant characteristics. Results: In this sample of 227 caregivers, 62.1% (n=141) screened above the SAS-SV risk threshold for problematic smartphone use. Significant determinants identified in multivariable logistic regression included female gender (AOR=5.83, 95% CI 1.58-21.45, p=0.008), unemployment (AOR=19.17, 95% CI 1.14-323.85, p=0.041), ethnicity (Brahmin/Chhetri: AOR=0.009, 95% CI 0.000-0.234, p=0.005; Janajati: AOR=0.015, 95% CI 0.001-0.420, p=0.014), chronic illness (AOR=0.009, 95% CI 0.000-0.514, p=0.022), frequent headaches (AOR=0.004, 95% CI 0.000-0.093, p<0.001), and occasional eye strain (AOR=0.081, 95% CI 0.009-0.748, p=0.027). Conclusion: In this sample, a high proportion of caregivers screened at risk for problematic smartphone use, with female gender and unemployment associated with higher adjusted odds. Given the cross-sectional design, these findings are preliminary and hypothesis-generating, and further longitudinal research is needed before screening or intervention strategies can be recommended.
