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
backgroundNational holiday breaks may involve less structured daily routines and cultural practices that favor excess energy intake, yet short-term changes in youth with intellectual disability (ID) following these breaks remain underexplored. This study examined changes in adiposity, muscular strength, and functional capacity following Chile's national holiday break among students with ID.
methodsIn this observational, single-group pre-post study, 49 students with mild-to-moderate ID (35 males, 14 females; 15.9 ± 4.0 years) were assessed before and after the holiday break. Anthropometric and adiposity indicators (body weight, waist [WC] and neck [NC] circumference, BMI, waist-to-height ratio [WHtR], submandibular skinfold [SS]), handgrip strength (absolute, relative) and functional capacity (countermovement jump, five-repetition sit-to-stand, timed up-and-go) were evaluated. Sex-differential changes were assessed using the time-by-sex interaction in mixed-model ANOVA, with Holm correction applied across outcomes within each domain. Within-sex pre-post comparisons were also adjusted using the Holm procedure.
resultsNo time-by-sex interaction remained significant after correction (all adjusted
conclusionsThe national holiday break was associated with a small increase in SS and an increase in handgrip strength, with the latter potentially reflecting a familiarization effect rather than a true physiological gain in strength. After correction for multiple comparisons, the findings do not support sex-specific conclusions; the observed pattern among females should therefore be considered hypothesis-generating and requires confirmation in larger, controlled studies.
