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
objectivesPuberphonia or mutational falsetto (MF) is seen more in males, and hormonal changes are considered to be among the aetiological causes. Therefore, the aim of this study was to investigate the molecules [G protein-coupled oestrogen receptor 1 (GPER-1), aromatase, 17-beta-hydroxysteroid dehydrogenase (17β-HSD), cyclic adenosine monophosphate (cAMP) levels] related to receptors and pathways in patients with MF.
methodsThe study included 30 MF patients and a control group of 30 healthy individuals. Voice recordings were made of the MF patients and acoustic analyses were applied. The serum GPER-1, aromatase, 17β-HSD, cAMP levels and TSH, estradiol, prolactin, progesterone, and testosterone levels were evaluated in venous blood samples.
resultsIn the MF patients, the GPER-1 level determined of mean 3.68 (1.95-4.26) pg/ml, 17 beta dehydrogenase of 5.25 (2.73-6.77) ng/ml, and cAMP of 24.62 (11.62-30.35) ng/ml were statistically signficantly higher than those of the control group (p = 0.008, p = 0.002, p = 0.003, respectively). The aromatase level in the MF patients was found to be 3.48 (2.01-4.91) and the difference between the two groups was not statistically significant (p = 0.067).
conclusionThe GPER-1, 17β-HSD, and cAMP levels were found to be higher in the MF patients than in the control group, suggesting that they could be of importance in the diagnosis and treatment of MF.
