Prospective BMI category change associated with cardiovascular fitness change.
Trial report in Medicine and science in sports and exercise, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeThe objective of this study was to test the relationship of change in body mass index (BMI) percentile score group (from sixth to eighth grade) with change in cardiovascular fitness (CVF), baseline BMIz-score, and CVF.
methodsChildren (3998 (92%)) in the HEALTHY trial provided complete data at the beginning of sixth and end of eighth grades. Height and weight were assessed according to standardized protocol. CVF was measured using the 20-m shuttle run. Changes in BMI percentile were categorized into five groups: increased a BMI category, stayed obese, stayed overweight, stayed at a healthy weight, and decreased a BMI category. Data were analyzed separately by sex, controlling for race, parental education, change in pubertal stage, and baseline BMIz-score and CVF.
resultsYouth (male and female) who lowered their BMI group or remained in the healthy or overweight groups had significantly larger increases in CVF than those in the stayed obese or increased a BMI category groups. However, these relationships accounted for a small percentage of variance (i.e., weak relationship). Staying obese was associated with the highest baseline BMIz-score, with the second highest among those who decreased a BMI category. BMI category change accounted for the most variance in baseline BMIz-score.
conclusionsChanges in BMI categories were substantially more strongly related to sixth-grade values of BMIz-score than to CVF changes. Because preexisting adiposity may inhibit adiposity change, changes in CVF and adiposity should be attempted before middle school.
