1 · What the graph read from it

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.

2 · The registry

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

objectiveUniversity students are at a developmental stage in which they may be more vulnerable to experiencing hikikomori (prolonged social withdrawal). Therefore, we focused on this population and examined the relationship between the tendencies toward and affinity for hikikomori in two studies.

methodsStudy 1 examined the relationship between the tendencies toward and affinity for hikikomori among 300 university students recruited online. Study 2 examined how stress coping, social support, and the affinity for hikikomori can explain hikikomori tendencies for a sample of 364 university students recruited offline. Both studies used the Adaptive Behaviors Scale for Hikikomori and Affinity for Hikikomori Scale, while Study 2 also used the Social Support Questionnaire and Coping Orientation to Problems Experienced Inventory.

resultsIn both studies, hierarchical multiple regressions indicated that, among the affinity components for hikikomori, a stronger desire for hikikomori was associated with higher hikikomori tendencies. Conversely, higher empathy for others with hikikomori was associated with lower hikikomori tendencies, contrary to the implicit assumptions. Higher social support, active coping skills, and the use of instrumental support explained lower hikikomori tendencies.

conclusionThese findings suggest that individuals at potential risk of developing hikikomori may be better identified by considering environmental (e.g., social support), behavioral (e.g., coping with stress), and cognitive and affective (e.g., desire for hikikomori) variables. Notably, empathy for others with hikikomori may reflect general empathic traits rather than being specifically related to hikikomori. Future longitudinal research should identify any causal relationships.
