Physical Fitness Cut-Points for Early Detection of Obesity Risk in Preschool Children.
Article in Obesity (Silver Spring, Md.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThis study aimed to establish cut-points for cardiorespiratory fitness, muscular strength, and speed-agility and to evaluate their ability to detect general and central obesity risk in preschool children aged 3-5 years.
methodsBriefly, 3179 Spanish preschoolers (52.8% boys) were evaluated. Physical fitness was assessed with the PREFIT battery. Anthropometry included BMI and waist circumference. Obesity risk was defined using age- and sex-specific percentiles according to criteria established by the World Health Organization and the International Diabetes Foundation. Receiver operating characteristic curve analyses were used to identify fitness cut-points.
resultsAge- and sex-specific cut-points were established. For cardiorespiratory fitness, cut-points ranged from 9.5 to 23.5 laps in boys and 6.5 to 21.5 in girls across the 3- to 5-year age range. Muscular strength cut-points ranged from z-scores of -1.5 to 2.2 in boys and -1.6 to 1.9 in girls. Speed-agility cut-points ranged from 18.8 to 14.9 s in boys and 19.9 to 15.3 s in girls. Predictive accuracy was moderate-to-high (AUC range: 0.61-0.74 for cardiorespiratory fitness, 0.59-0.80 for strength, 0.49-0.71 for speed-agility).
conclusionsThis study provides fitness cut-points for detecting general and central obesity risk in preschoolers. Early integration of physical fitness assessments into health monitoring may facilitate early identification of obesity risk.
