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
introductionAging has a significant impact on health, leading to changes in body composition and physical functionality in older adults.
objectiveGiven the relevance of this topic, the aim of this study was to analyze the effects of vitamin D supplementation combined with physical exercise over a 12-week period on body composition and metabolic profile in elderly women.
methodsThe study followed a clinical approach, employing a randomized, double-blind, placebo-controlled trial, in accordance with the guidelines established by the Consolidated Standards of Reporting Trials (CONSORT), conducted at the Movement Studies Laboratory in São Paulo, Brazil. Analyses were performed using an intention-to-treat approach with random effects regression models. The study sample consisted of 46 elderly individuals, divided into two groups with 23 participants each. The experimental group received vitamin D3 supplementation at a dose of 49,000 IU/week, while the placebo group received seven capsules of the same size, volume, and color, containing lactose but no vitamin D3.
resultsAfter analyzing the results, it was observed that the groups were homogeneous in terms of age (p = 0.7658) and BMI (p = 0.5904). The results showed differences in 25-OH vitamin D levels (p < 0.001) between the groups over time.
conclusionIn conclusion, vitamin D supplementation successfully increased serum levels but failed to provide additional benefits for muscle mass or metabolic markers compared to resistance training alone.
