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
Objectives: Although social network services (SNS) are prevalent globally, the relationship between SNS use and loneliness remains complex, particularly regarding qualitative behavioral patterns. This study examined associations between specific SNS behaviors and loneliness among Seoul adults and explored differences by age and digital literacy. Methods: Data from the 2024 Seoul Survey were analyzed (n=34 142; mean age, 52.3 years). Loneliness was assessed with 2 items measuring isolation in family and non-family relationships. Five SNS behavioral domains were examined: active use, information-seeking use, communication priority, social comparison, and exclusionary feeling. Digital literacy was dichotomized using an 8-item scale, with scores ≥6 considered high. Multivariable logistic regression estimated adjusted associations. Results: Overall SNS use was associated with lower odds of loneliness than non-use (adjusted odds ratio [aOR], 0.90; 95% confidence interval [CI], 0.83 to 0.98). However, higher odds were observed for specific SNS behaviors compared with non-use: active use (aOR, 1.24), communication priority (aOR, 1.26), social comparison (aOR, 1.50), and exclusionary feeling (aOR, 1.66); information-seeking use was not significant (aOR, 1.11). A dose-response pattern peaked at 3 problematic behaviors (aOR, 3.21; 95% CI, 2.82 to 3.65). Associations between SNS behaviors and loneliness were stronger among adults aged ≥60 years and participants with high digital literacy. Conclusions: Although overall SNS use was associated with modestly lower odds of loneliness, qualitative SNS engagement-particularly problematic behaviors-was strongly associated with higher odds. Older adults and participants with high digital literacy appeared particularly vulnerable when performing problematic SNS behaviors, underscoring the need for behavior-focused, population-tailored education and interventions.
