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

backgroundThe neuronal ceroid lipofuscinoses (NCLs) are a group of disorders characterized by neurodegeneration and intracellular accumulation of an auto-fluorescent lipopigment. Together, NCLs represent the most common cause of cerebral neurodegenerative disease in children. CLN3 disease, the classic juvenile-onset form (JNCL) due to mutations in CLN3, is characterized by progressive vision loss, epilepsy, dementia, behavioral difficulties, and motor impairment. The Unified Batten Disease Rating Scale (UBDRS) is a disease-specific rating scale that was developed to assess disease severity in 4 domains: physical, behavior, seizures, and functional capability. Validity and reliability of the UBDRS has been established in a large North American cohort of over 130 individuals. The purpose of this study was to determine whether the UBDRS is valid and reliable when tested in an independent sample.

methodsOver the course of one week, 13 individuals with genetically confirmed CLN3 disease were evaluated with the UBDRS by 5 examiners at the University Medical Center Hamburg Eppendorf (UKE). One rater (JWM), one of the developers of the UBDRS, served as the reference standard. The other 4 raters were physicians with expertise in various forms of Batten Disease. After a formal training session, 13 individuals (age 16.5 ± 5.6 yrs) were evaluated simultaneous in parallel by the 5 raters. Inter-rater reliability of the Physical subscale was assessed with Intra-class Correlation (ICC) analysis. The relationship between age and severity was assessed and compared to previously published data from the North American cohort.

findingsThe ICC among the 5 independent raters was 0.92, demonstrating excellent inter-rater reliability. The individual correlations of each UKE rater compared to the reference standard rater were all >0.95. The average UBDRS Physical Subscale score in this sample was 28 ± 21 (mean ± SD) with a range from 1 to 61. When evaluated as a function of participant age, the slope was 3.06 points/year (R

interpretationWe have shown excellent interrater reliability for the UBDRS as a clinical rating scale for CLN3 disease in a sample independent from previous work. The results of this study are comparable to those published by Kwon et al., 2011 in a North American cohort showing a slope of 2.86 points per year with a 95% CI of 2.27-3.45 (N = 82). Our results demonstrate excellence inter-rater reliability after training a new group of raters and provide additional evidence for construct validity of the UBDRS. The UBDRS is a valid and reliable rating scale that can used by trained raters to assess the severity and rate of progression of CLN3 disease.
