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
introductionMetabolic dysfunction-associated fatty liver disease (MAFLD) is a growing public health concern worldwide. Emerging evidence suggests that sleep disturbances may contribute to metabolic dysfunction and hepatic steatosis; however, data from rural Indian populations remain limited. This study assessed the association between sleep quality, sleep duration, and MAFLD risk among adults attending a rural primary healthcare facility in North India.
methodsA community-based analytical cross-sectional study was conducted among 550 adults attending the Rural Health Training Center of a tertiary care teaching institution in Haryana, India. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and participants were classified as having good (PSQI ≤ 5) or poor (PSQI > 5) sleep quality. Sleep duration was categorized as <6 hours, 6-8 hours, or >8 hours per night. MAFLD risk was estimated using a validated non-laboratory risk assessment score and categorized as low (<8 points) or high (≥8 points). Multivariable logistic regression was performed to evaluate the association of sleep-related factors with high MAFLD risk after adjustment for sex, smoking status, alcohol consumption, and dietary pattern.
resultsThe mean age of participants was 42.6 ± 13.5 years, and 56.4% were female. Poor sleep quality was observed in 210 (38.2%) participants, while 174 (31.6%) were classified as having high MAFLD risk. High MAFLD risk was significantly more common among participants with poor sleep quality than among those with good sleep quality (47.1% vs. 22.1%; p < 0.001). Participants sleeping <6 hours per night had the highest prevalence of high MAFLD risk (44.6%) compared with those sleeping 6-8 hours (28.5%) or >8 hours (26.4%) (p = 0.002). After adjustment for sex, smoking status, alcohol consumption, and dietary pattern, poor sleep quality (adjusted odds ratio (AOR): 2.68; 95% CI: 1.82-3.95) and short sleep duration (AOR: 1.71; 95% CI: 1.10-2.64) remained independently associated with high MAFLD risk. The PSQI score demonstrated acceptable discriminatory ability for identifying high MAFLD risk (AUC = 0.71; 95% CI: 0.65-0.77).
conclusionsPoor sleep quality and short sleep duration were independently associated with high MAFLD risk among adults in a rural North Indian primary care setting. These associations remained significant after adjustment for selected demographic and lifestyle factors. Incorporating sleep assessment into routine metabolic risk screening may provide a simple, low-cost strategy for identifying individuals at increased risk of MAFLD.
