The effect of dietary supplements on the quality of life of retired professional football players.
Trial report in Global journal of health science, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Professional football players may experience negative health consequences when they retire such as chronic pain, cognitive problems as well as other consequences of sports-related injuries. The purpose of this pilot study is to determine the effects of dietary supplementation with multiple nutrients on the quality of life of retired football players. Fifteen retired players received daily supplementation of fish oil with cholecalciferol, antioxidants, natural vitamins and minerals, polysaccharides and phytosterol-amino acid complex for 6 months. Using an open-labeled repeated measures design, volunteers completed self-report assessment measures at baseline, 1, 3 and 6 months. Outcome measures were CDC HRQOL-4, WHOQOL-BREF, POMS, MFQ and pain self-assessment. General health rating improvement on CDC HRQOL-4 from month 1 was sustained to month 6 (p<0.0001). Mental health days improved at 6 months (p<0.05). WHOQOL-BREF showed increased health satisfaction at all measurement points (p<0.05) and the Physical and Psychological Domain Scores at 6 months (p<0.05). MFQ General Rating of Memory improved at 3 and 6 months (p<0.05). Vigor scale in POMS was significant at 3 months (p<0.05). Decreased pain was noted only for the elbow at month 1 and the knee at month 3 (p<0.05). No adverse events were reported. Results of this study offer preliminary insight into using dietary supplements to support and optimize quality of life in retired football players. Further research using a placebo-controlled design is needed to characterize the potential benefit to physical and psychological well-being of multiple dietary supplementations for this cohort.
