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
Sleep deficiency is becoming increasingly common among adolescents and may lead to aggressive behaviour. This study investigated the association between sleep deficiency and fighting among 1946 school-aged adolescents (mean age: 12.2 ± 0.47 years) in Ningbo city through a two-year longitudinal study and explored the mediating roles of loneliness, sadness, and nervousness. A total of 552 (28.3%) reported sleep deficiency at baseline. During the follow-up period, 347 (17.8%) adolescents engaged in fighting. Sleep deficiency was significantly associated with an increased likelihood of fighting (OR: 1.91, 95% CI: 1.45-2.52) after adjusting for confounders. Compared with boys, girls with sleep deficiency presented a greater risk of fighting (OR: 2.61, 95% CI: 1.44-4.73 for girls; OR: 1.74, 95% CI: 1.27-2.39 for boys). This association persists among adolescents with unhealthy lifestyles. Loneliness partially mediated this relationship (indirect effect β = 0.013, P < 0.05, effect ratio = 12.26%), whereas sadness and nervousness had no significant mediating effect. Studies have shown that sleep deficiency independently predicts adolescent fighting behaviour, with loneliness playing a key mediating role. Interventions that improve sleep hygiene, reduce loneliness, and address lifestyle likelihood factors may help reduce violent behaviour in adolescents.
