1 · What the graph read from it

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.

2 · The registry

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

Background: This study investigated the nutritional knowledge and prevalence of dietary supplements (DSs) among Iranian bodybuilders. Methods: This cross-sectional research study involved sampling 648 bodybuilding clubs in Iran. A researcher distributed questionnaires among clubs in various regions and analyzed categorical variables, DS, nutritional knowledge, and sports nutrition data from 160 bodybuilders aged 18 and above in Iran. The analysis was conducted using the results obtained from a quantitative questionnaire. Results: There was a significant relationship between DS use and gender ( Conclusions: This study concluded that fitness coaches and registered dietitians/nutritionists were the most common information sources for bodybuilders. It also revealed a moderate level of nutrition knowledge among bodybuilders. The most commonly used DS were vitamins C, D, and whey protein. Also, gender, bodybuilding history, and exercise sessions had a significant relationship with the prevalence of DS. However, the study also revealed some concerning findings; bodybuilders commonly experienced adverse side effects such as skin rashes, increased liver enzymes, and hair loss.
