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
Background: Dental schools can be a stressful place that may impair students' performance. This stress can be related to several salivary biomarkers such as salivary cortisol. Also, emotional intelligence (EI) is one of the important factors in adapting people to the environment. Purpose: This research investigated the relationship between stress and EI with academic progress in Qom's Dental School students. Materials and Method: This cross-sectional (descriptive-analytical) study measured salivary cortisol using the enzyme-linked immunosorbent assay (ELISA) method. It involved 88 dental students in their third to sixth years. The required data were gathered using two standard questionnaires, namely Wang and Law's EI scale and the dental environment stress questionnaire. Pearson's correlation coefficient and independent t-test were used for data analysis. Results: A total of 88 students participated in this research, of which 54.5% were female. Salivary cortisol had no relationship with EI or stress from the dental environment ( Conclusion: This study found no association between salivary cortisol levels, dental environment stress, and EI. Additionally, cortisol levels were inversely related to students' annual grade point average. Conversely, there was no correlation between annual grade point average and EI.
