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: To examine coffee consumption patterns and their associations with sleep quality indicators among Saudi youth, and to identify independent predictors of poor sleep outcomes using multivariate regression. Methods: A cross-sectional study was conducted among 1458 consenting Saudi youth (aged 16-30 years) using an online questionnaire adapted from the Pittsburgh Sleep Quality Index (PSQI). Chi-square tests examined associations between coffee consumption patterns (type, timing, pre-bedtime cessation) and sleep variables. Binary logistic regression identified independent predictors of late bedtime (sleeping after midnight), adjusting for demographic covariates. Results: The sample was predominantly female (69.4%, n = 1012) and aged 18-22 years (65.7%, n = 958). Evening/night-time coffee consumption was a strong independent predictor of sleeping after midnight (OR = 3.04, 95% CI: 2.30-4.02, p < 0.001), adjusting for cessation strategy, sex, age, and student status. Chi-square analyses confirmed that coffee consumption timing showed highly significant associations with bedtime patterns (χ Conclusions: Temporal aspects of coffee consumption demonstrate stronger and more consistent associations with sleep quality than coffee type selection. Evening coffee use is an independent risk factor for delayed sleep timing. Strategic timing interventions may be more effective than content-based restrictions for improving sleep health in Saudi youth.
