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
objectiveYellow September (YS) (Setembro Amarelo) is a Brazilian suicide prevention campaign launched in 2015, however, its effectiveness at reducing mortality is still unknown. This is an ecologically interrupted time series study that analyzed the trend in suicide rates in Brazil between 2011 and 2019 and its association with the implementation of YS at a national level.
methodsA segmented interrupted series regression analysis was performed, using a generalized linear Poisson model, with correction for seasonal trends. Data were provided by the Mortality Information System (Sistema de Informações Sobre Mortalidade [SIM]).
resultsThere was an increase in the annual rates of suicide deaths between 2011 and 2019, with 4.99 and 6.41 suicides per 100,000 inhabitants, respectively. The null hypothesis, that the YS did not change the historical trend of growth in suicides in Brazil after its implementation, was confirmed. However, there was a significant increase of 6.2% in the risk of mortality in 2017 and a significant increase of 8.6% in 2019.
conclusionThe results are consistent with the literature, which proposes that campaigns focused solely on publicity in the media generate unsound findings regarding the effective reduction in the number of deaths by suicide. The lack of initiatives involving multisectoral actions may explain the failure of YS to change rates of death by suicide. Therefore, implementation of new lines of action focused on training professionals and expanding the care network could make it an effective instrument for reducing mortality from suicide.
