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
backgroundPhysical inactivity (PI) is a major contributor to adiposity and cardiometabolic morbidity.
objectiveTo synthesize evidence of the association between PI and childhood overweight/obesity (OV/OB) and metabolically unhealthy obesity (MUO; OB accompanied by cardiometabolic abnormalities) risk.
methodsA systematic review and meta-analysis of prospective epidemiological studies and randomized controlled trials (RCTs) was performed following PRISMA guidelines (PROSPERO ID: CRD42023482960). Studies conducted in Western countries with 2-19-year-old participants, PI-related exposures (time/frequency of engagement in various sedentary behaviors) and interventions (targeting PI reduction), OV/OB-/MUO-related outcomes and ≥ 12-month follow-up were extracted from PubMed and Scopus (publication timeframe: 01/01/2013-30/06/2024). Study quality was assessed through risk of bias (RoB).
resultsAmong 86 prospective epidemiological studies with OV/OB-related outcomes (42% high-RoB), PI was evaluated objectively (accelerometry) in 34 and subjectively (questionnaires) in 57 (29% and 68% reported detrimental associations, respectively). In random-effects meta-analysis, subjectively-assessed total screen time was positively associated with body mass index (BMI) [n = 4; beta (95%CI): 0.116 (0.037, 0.195) kg/m2] and BMI z-score [n = 8; beta (95%CI): 0.032 (0.002, 0.063)], while television viewing was positively associated with BMI [n = 3; beta (95%CI): 0.227 (0.025, 0.428) kg/m2], BMI z-score [n = 4; beta (95%CI): 0.042 (0.007, 0.077)] and OV/OB incidence [n = 5; logRR (95%CI): 0.089 (0.044, 0.133)]. The sole RCT (low-RoB) indicated a beneficial effect of reducing sedentariness on anthropometric indices. Two prospective epidemiological studies (high-RoB) suggested positive associations between subjectively-assessed total screen time and MUO-related outcomes.
conclusionsScreen time is positively associated with indicators of childhood OV/OB risk, while limited evidence also supports its detrimental role in MUO.
