Impact of exercise changes on body composition during the college years--a five year randomized controlled study.
Trial report in BMC public health, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00521235 (Effects of Different Working Condition on Risk Factors in Dentists Versus Trainers. A Combined Crosssectional and Longitudinal Trial With Student and Senior Employees.), which is not on this map. Cited by 7 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.

Abstract
backgroundObservational studies have consistently reported severe weight gains during the college years; information about the effect on body composition is scarce, however. Thus, the aim of the study was to determine the effect of exercise changes on body composition during 5 years at university.
methodsSixty-one randomly selected male and female dental (DES; 21 ± 3 years., 22 ± 2 kg/m(2)) and 53 sport (physical education) students (SPS; 20 ± 2 years., 22 ± 3 kg/m(2)) were accompanied over their 5-year study program. Body mass and body composition as determined via Dual-Energy x-ray-absorptiometry (DXA) at baseline and follow-up were selected as primary study endpoints. Confounding parameters (i.e., nutritional intake, diseases, medication) that may affect study endpoints were determined every two years. Endpoints were log-transformed to stabilize variance and achieve normal distributed values. Paired t-tests and unpaired Welch-t-tests were used to check intra and inter-group differences.
resultsExercise volume decreased significantly by 33% (p < .001) in the DES and increased significantly (p < .001) in the SPS group. Both cohorts comparably (p = .214) gained body mass (SPS: 1.9%, 95%-CI: 0.3-3.5%, p = .019 vs. DES: 3.4%, 1.4-5.5%, p = .001). However, the increase in the SPS group can be completely attributed to changes in LBM (2.3%, 1.1-3.5%, p < 0.001) with no changes of total fat mass (0.6%, -5.0-6.5%, p = 0.823), while DES gained total FM and LBM in a proportion of 2:1. Corresponding changes were determined for appendicular skeletal muscle mass and abdominal body-fat. Maximum aerobic capacity increased (p = .076) in the SPS (1.6%, -0.2-3.3%) and significantly decreased (p = .004) in the DES (-3.3%, -5.4 to -1.2%). Group differences were significant (p < .001). With respect to nutritional intake or physical activity, no relevant changes or group differences were observed.
conclusionWe conclude that the most deleterious effect on fatness and fitness in young college students was the pronounced decreases in exercise volume and particularly exercise intensity.
