Prevalence of Congenital Anomalies in Iran.
Article in Archives of Iranian medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAnnually, 3-8 million infants are born with congenital anomalies worldwide, ranging from 3% to 7% of births in different countries. This study aimed to investigate the nationwide epidemiological features of birth defects in Iran.
methodsThis cross-sectional study was conducted in six major regions across Iran. The data sources were the maternity facilities affiliated with regional universities of medical sciences. All children were examined by obstetricians, pediatricians, or midwives at birth, and newborns were followed until discharge from the facility for health status, maturity, and congenital defects.
resultsA total of 138,643 births were registered in the maternity facilities across the study regions. Among these newborns, 3,458 cases were diagnosed with congenital anomalies, representing an overall prevalence rate of 249.4 per 10000 births (95% CI: 241.2-257.8). Genital organ anomalies exhibited the highest rates of defects in the country with 92.7 per 10000 births (95% CI: 86.4-98.9), followed by limb anomalies at 83.3 per 10000 births (95% CI: 77.4-89.3). The prevalence of respiratory system, chromosomal, and urinary tract anomalies was less than 10 per 10000 births.
conclusionUntil a national registry for congenital anomalies is established, this study provides essential data on the magnitude of the health problems caused by congenital anomalies in Iran. The findings would be vital for planning and evaluating antenatal screening for birth defects, particularly for high-risk groups and regions in the country.
