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
backgroundAdolescence is a complicated and sensitive period, and proper nutrition in this period of life can influence the quality and quantity of growth and maturity. The aim of the present study is to determine the factors associated with healthy eating behavior based on the developed theory of planned behavior in adolescents. MATERIALS AND
methodsThis is a descriptive-correlational study in which 400 female students of the first grade of high school in Bandar Anzali participated. Among the junior high schools in this city, two schools were randomly selected and sampling was done using census method. Data collection tool was Healthy Eating Behavior questionnaire based on Theory of Planned Behavior, which includes three sections of demographic information, constructs of Theory of Planned Behavior, including attitude toward behavior, subjective norms, perceived behavioral control, and behavioral intention, and food behavior, and food habits questionnaire. The scale was evaluated and confirmed by content validity ratio, content validity index, and alpha coefficient.
resultsAs shown by linear regression analysis, the developed theory of planned behavior is able to predict 26% of the variance of healthy eating behavior, and this predictive power is related to the constructs of behavioral intention, attitude, and habits.
conclusionsIn the present study, adding the variable of habits to the theory of planned behavior showed that this variable is very effective in predicting healthy eating behavior in adolescents, just like the constructs of behavioral intention and attitude. Therefore, it is suggested to carry out educational interventions based on the developed theory of planned behavior with the focus of the mentioned structures.
