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
aimsDealing with the aging population crisis is one of the priorities of research and intervention in Iran, which requires scientific and comprehensive persuasion of families to have more children. This study investigated the relationship between having siblings and child' developmental status. METHODS AND MATERIALS: Using the data from the PERSIAN birth cohort study, 611 two-year-old children who were residents of Semnan were investigated. The studied information included the gender of the child, the number of siblings, and the developmental test score of the child at the age of two. The assessment of the child's development was performed using the Ages and Stages Questionnaires (ASQ).
resultsAmong 294 girls and 317 boys, 352 (57.6%) had no siblings, and the remaining group had between 1 and 5 siblings. The mean (± standard deviation) of the developmental score in children who had siblings (281 ± 23) was higher than children who did not have siblings (278 ± 21) (Cohen's d = .14,
conclusionsHaving siblings may help a child develop social and personal skills probably by increasing family social interaction. Emphasizing the positive impact of having brothers and sisters on a child's growth and development can be a motivating factor for having more children in the family.
