Spatial clusters and temporal trends of cutaneous malignant melanoma mortality in Spain.
Article in The Journal of international medical research, 2025. 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
objectiveTo analyse time trends in mortality due to cutaneous malignant melanoma (CMM) in Spain between 1980 and 2020, and to identify possible spatial clusters of provinces with an excess risk of CMM mortality during the period 2011-2020.
methodsJoinpoint regression models were used to assess temporal trends in data from the Spanish National Institute of Statistics. Crude rates, standardized mortality ratio (SMR), smoothed relative risk (RR), and posterior probabilities (PP) of RR >1 during the period 2011-2020 were calculated. The Global Moran I index was used to assess global spatial autocorrelation.
resultsTwo time-periods were detected in women: a significant increase during 1980-1994 (annual percent change [APC], 6.5% per year) and rate stabilization during 1994-2020 (nonsignificant APC, -0.17%). A similar pattern was observed in men, with three periods comprising a significant increase during 1980-1985 (APC, 16.59%), a slowing of the increase during 1985-1998 (APC, 4.40%), and stabilization during 1998-2020 (nonsignificant APC, 0.37%). Spatial analysis showed greater spatial heterogeneity with an east-north pattern in men compared with the pattern in women, which tended to be concentrated in north-western areas.
conclusionMortality rates associated with CMM in Spain have remained stable in recent years. There were provincial clusters that exhibited an excess risk of mortality from CMM, with different patterns according to sex.
