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

rationaleDanon disease (DD) is an X-linked lysosomal storage disorder caused by LAMP2 variants, with males presenting more severe phenotypes. However, evidence for genotype-phenotype correlation remains limited. This study reports 2 male DD patients with distinct LAMP2 mutations to clarify mutation-specific prognostic differences. PATIENT CONCERNS: A 15-year-old male: chest tightness and palpitations, creatine kinase (CK) 3867 U/L, and hypertrophic cardiomyopathy. A 12-year-old male: exertional dyspnea and syncope, left ventricular ejection fraction 36%, left ventricular thrombus, and CK 5210 U/L. DIAGNOSES: Both were diagnosed with DD via genetic testing: the 15-year-old had a LAMP2 IVS6 + 1G > T splice mutation, and the 12-year-old carried a LAMP2 exon 1 deletion.

interventionsThe 15-year-old underwent heart transplantation followed by immunosuppressive therapy. The 12-year-old received only symptomatic treatment without transplantation. OUTCOMES: The 15-year-old had normal cardiac function and normalized CK levels during 24-month posttransplant follow-up. The 12-year-old died of heart failure 8 months after diagnosis. LESSONS: LAMP2 mutation types correlate with DD severity. Heart transplantation improves prognosis in severe cases, emphasizing the importance of early diagnosis and intervention.
