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

objectiveTo establish a birth rate for catecholaminergic polymorphic ventricular tachycardia (CPVT) diagnosed in childhood and observe trends in presentation and management.

designRetrospective cohort study.

settingThe Inherited Arrhythmia Clinic at The Sydney Children's Hospitals Network, a paediatric tertiary referral network, New South Wales (NSW), Australia (2002-2021), where there are 86 000-97 000 live births/year. PATIENTS: Children diagnosed with CPVT aged 0-16 years.

interventionsClinical data were extracted and evaluated for trends. Using birth year data, the birth rate of CPVT detected in childhood was calculated.

main outcome measuresBirth rate of CPVT detected in childhood in NSW (with post hoc comparison to New Zealand), trends in diagnosis and management, and outcome at last follow-up.

results32 children in NSW were diagnosed with CPVT between 2002 and 2021 (0-16 years, median 9 years, 14 (54%) female). Of these, 28 (88%) presented with symptoms (cardiac arrest 20/32, 62.5%) and four (12%) were identified through family screening. Relevant genetic variants were identified in 25/31 (78%). During follow-up (median 4.5 years), symptomatic cardiac events (death n=1) occurred in 10 (33%), largely related to suboptimal adherence or monotherapy beta blocker. In NSW, CPVT was diagnosed during childhood following 1 in 65 000 live births (95% CI 1 in 91 000 to 1 in 46 000). In New Zealand, the corresponding figure was 1 in 84 000 live births (95% CI 1 in 138 000 to 1 in 52 000).

conclusionsThe rate of infants born who are later diagnosed with CPVT in childhood is approximately 1 in 65 000 live births. Suboptimal adherence and beta blocker therapy without flecainide appeared related to recurrent cardiac events.
