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
purposeThe association between the use of mobile phones use and the risk of brain cancer remains controversial. The aim of this study is to describe trends in the incidence of central nervous system (CNS) cancers in Spain and its possible relationship with mobile phone use.
methodsTrends and trend changes from 1985 to 2015 in adjusted incidence rates of CNS cancers by sex, age (adults and children), site, and histological type were assessed using data from 14 general and paediatric cancer registries.
resultsThe study included 20,325 CNS malignancies in adults and 2,372 in children. For adults, the overall rate of malignant brain tumours showed a slight increase of 0.2% (95% CI: 0.1 - 0.4) per year. This increase was concentrated in the early years up to 1996 (1.7% per year, 95% CI: 0.9 - 2.6) followed by 20 years of a non-significant slight decline of -0.1% (95% CI: -0.4 - 0.1) per year until 2015. In children, an increase of 7.6% (95% CI: 2.4 - 13.1) per year until 1991 followed by a decrease of -1.0% (95%CI: -1.7 - -0.3) per year until 2015 was observed. This increase in the incidence in 1980s and early 1990s could be explained by diagnostic improvements especially in imaging techniques implemented during these years.
conclusionThe present findings do not support a possible relationship between the use of mobile phones and the incidence of malignant brain tumours. However, the possibility of the presence of a weak correlation or that a longer latency period would be needed to observe a possible ecological correlation cannot be discarded.
