1 · What the graph read from it

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.

2 · The registry

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

Objective: Inherited kidney diseases (IKDs) significantly contribute to chronic kidney disease (CKD), particularly in regions with high consanguinity rates. Despite the increasing availability of next-generation sequencing, evidence regarding its diagnostic and clinical effectiveness in adult populations remains limited. This study evaluated the diagnostic yield and clinical implications of genetic testing in adults with suspected IKD. Materials and Methods: A retrospective analysis of 63 adults who underwent genetic evaluation for unexplained or familial CKD was performed. Genetic testing used sequencing-based methods to identify and analyze genes relevant to the clinical phenotype. Clinical and demographic factors, diagnostic yield, genetic etiologies, and clinical utility were documented. Results: The genetic diagnostic yield in this predominantly female cohort, with a mean age of 37.2±14.9 years, was 54.0%. Autosomal recessive disorders were the most common inheritance pattern (61.8%). Alport spectrum disorders represented the primary etiology (67.6%), followed by ciliopathies/cystic diseases (14.7%). The diagnostic yield varied across clinical diagnostic groups, with Alport spectrum disorders showing the highest yield and other glomerulopathies showing the lowest yield (75.0% vs. 4.5%, p<0.001). Extrarenal manifestations were significantly associated with a positive genetic diagnosis (32.4% vs. 0.0%, p<0.001). Genetic findings confirmed the clinical diagnosis in 70.6% of positive cases, reclassified the diagnosis in 17.6%, and identified an alternative genetic diagnosis in 11.8%. Conclusion: Genetic testing demonstrated a high diagnostic yield and considerable clinical utility in Turkish adults with suspected IKD. These findings support the integration of genetic evaluation into routine nephrology practice, particularly for patients with syndromic features and a notable family history.
