Unveiling the hidden burden: challenges and spectrum of inborn errors of metabolism in LMICs.

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
backgroundInborn Errors of Metabolism (IEM) are an important cause of morbidity and mortality in neonates and children, particularly in resource-limited settings. In Pakistan, comprehensive data on IEMs remain scarce, contributing to underdiagnosis and delayed interventions.
methodsThis retrospective study reviewed medical records of children presenting with suspected IEMs to a tertiary care hospital in Islamabad between January 2014 and May 2019. Cases were identified through medical record coding, and diagnoses were based on biochemical tests and enzyme assays.
resultsA total of 64 patients were identified. Diagnoses included glycogen storage disorders (n = 15), galactosemia (n = 3), Gaucher's disease (n = 3), mucopolysaccharidosis (n = 4), congenital adrenal hyperplasia (n = 19), and unspecified IEMs (n = 20). One case was initially misdiagnosed as drug overdose, while six cases lacked sufficient data for classification. Delayed diagnosis, limited availability of genetic testing, and financial constraints resulted in predominantly symptomatic management. Outcomes were poor, with many patients succumbing during care.
conclusionThis study highlights the urgent need for improved diagnostic capacity for IEMs in Pakistan. The establishment of genetic testing facilities, including whole-exome sequencing and a cost-effective IEM gene panel, is critical to enable timely and accurate diagnosis, improve clinical management, and ultimately reduce morbidity and mortality in affected children. IMPACT: The study highlights the significant burden of Inborn Errors of Metabolism (IEM) in a low-middle-income country, emphasizing the challenges of late diagnosis, lack of genetic diagnostic tools, and poor follow-up due to financial constraints. This study adds critical insights into the prevalence, spectrum, and clinical outcomes of IEMs in Pakistan. It identifies specific gaps in diagnostic infrastructure, management practices, and healthcare accessibility in resource-limited settings. The study emphasizes the importance of addressing diagnostic and financial barriers to reduce the morbidity and mortality associated with IEMs in Pakistan.
