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

backgroundAutosomal dominant tubulointerstitial kidney disease (ADTKD) is characterized by tubular atrophy, interstitial fibrosis, and progressive kidney dysfunction. Its causative genes include UMOD, MUC1, REN, HNF1B, and SEC61A1. ADTKD contributes to unexplained chronic kidney disease (CKD), and many cases remain genetically undiagnosed. This study aimed to elucidate the clinical features of patients genetically diagnosed with ADTKD in Japan.

methodsWe included individuals with suspected congenital anomalies of the kidney and urinary tract, nephronophthisis, polycystic kidney disease, or ADTKD. Genetic analyses using direct sequencing, short-read next-generation sequencing (SRS), and/or long-read next-generation sequencing (LRS) were performed on 1097 families. Patients with ADTKD-HNF1B were excluded due to prior reporting.

resultsVariants in UMOD, MUC1, REN, and SEC61A1 were identified in 52 patients from 40 families (18, 16, 5, and 1 family, respectively). The median age at diagnosis was 38.5 years, and the urinary protein-to-creatinine ratio was 0.05 g/gCr. End-stage kidney disease was present at diagnosis in 37% of patients. Genetic testing was performed in 58% due to suspected ADTKD based on pathology or clinical course and in 38% due to unexplained CKD. Kidney biopsies were performed in 55%, with ADTKD confirmed pathologically in 41%. SRS and LRS were used in 55% and 30% of all families, respectively; for ADTKD-MUC1, 75% of families were analyzed using LRS.

conclusionsClinical and pathological diagnosis of ADTKD remains challenging, emphasizing the importance of comprehensive genetic testing. Enhanced access to advanced genetic testing such as LRS is essential to improve diagnostic precision and management.
