Temporal clustering of neuroblastic tumours in children and young adults from Scotland.
Article in Environmental health : a global access science source, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundNeuroblastic tumours (neuroblastoma and ganglioneuroblastoma) are the most common childhood solid tumours outside the central nervous system, with a median age of diagnosis of 2 years. Temporal clustering of neuroblastic tumours in northern England and Ontario, Canada has been previously reported.
methodsWe extracted data from the Scottish Cancer Registry to determine whether there was evidence of temporal clustering of neuroblastic tumours. Cases diagnosed in children and young adults aged 0-24 years between 2000 and 2020 were analysed. A modified version of the Potthoff-Whittinghill method was used to test for temporal clustering. Estimates of extra-Poisson variation (EPV) and standard errors (SE) were derived.
resultsOne hundred and sixty-one cases of neuroblastic tumours, aged 0-24 years, were diagnosed during the study period. Overall, there was statistically significant temporal clustering between years within the full study period (EPV = 9.13, SE = 0.22, P < 0.001). In addition, for cases aged < 18 months, there was significant temporal clustering between months within quarters (EPV = 0.77, SE = 0.41, P = 0.044). For cases aged 18 months - 24 years, there was significant temporal clustering between fortnights within months (EPV = 1.00, SE = 0.47, P = 0.012).
conclusionsThe finding of temporal clustering is consistent with the involvement of one or more, as yet unknown, transient environmental agents in the aetiology of neuroblastic tumours.
