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
The 2024 flooding in Rio Grande do Sul, Brazil, was the worst natural disaster in the history of the state. We aimed to examine the impact of flooding on individuals' lives and depressive and anxiety symptoms among residents of Rio Grande do Sul. We analyzed data from the Prospective Study on Mental and Physical Health in Adults (PAMPA), conducted with adults from Rio Grande do Sul. Participants completed an online questionnaire between September and November 2024. Depressive and anxiety symptoms were assessed using the Hospital Anxiety and Depression Scale, in which scores above eight indicated moderate-to-severe symptoms. The flooding impact was measured via 12 questions on direct and indirect consequences (e.g., energy shortages, displacement, material losses) and categorized into tertiles: low, medium, and high burden. Among the 2,494 participants (mean age: 43.1 ± 15.1 years; 69.6% women), 83.8% reported being affected by the flooding, and 29.7% experienced a high burden. Displaced participants were more likely to report anxiety (PR = 1.24; 95%CI: 1.09, 1.41) and depressive symptoms (PR = 1.32; 95%CI: 1.10, 1.58). High burden was associated with anxiety (PR = 1.72; 95%CI: 1.49, 1.97) and depressive symptoms (PR = 1.52; 95%CI: 1.25, 1.86). Moderate-to-severe anxiety and depressive symptoms were 77% and 129%, respectively, higher than expected. The 2024 flooding had a profound impact on mental health, in which individuals who experienced a greater burden had higher rates of moderate-to-severe symptoms of anxiety and depression.
