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
backgroundThe war in Gaza, coupled with severe restrictions on humanitarian access and assistance, have led to a rapid and large-scale exacerbation of food insecurity (FI) and water insecurity (WI) in Gaza, which can cause a myriad of deleterious effects on both physical and mental health. Previous evidence suggests that environmental stressors (such as FI and WI), coupled with lack of support, can compromise coping ability and trigger psychosis. Elucidation of these pathways can inform efforts to reduce the incidence of psychosis in war settings in particular, and in global communities more generally. This study aimed to assess the mediating role of social support on the association between food-water insecurities and psychotic experiences (PEs).
methodsThis study was carried-out over a period of one month (September 2024) by using a free online form builder. Data were collected at a single time point using snowball sampling. A total of 476 adults aged 18–35 years and living in Gaza at the time of the survey took part in this study. The Prodromal Questionnaire- Brief, the Food Insecurity Experience Scale, the Four-Item Household Water Insecurity Experiences Scale, and the Single Item Measure of Social Supports have been administered to participants.
resultsA total of 110 participants (23.1%) reported low tangible social support (i.e., having no or 1 person in the social support network), 27.3% were classified as moderately-to-severely food insecure and 41% were categorized as water-insecure. The mediation analysis was adjusted for the following covariates: marital status, living arrangement and age. Higher food-water insecurity experiences were significantly associated with lower social support. Higher food-water insecurity experiences were also significantly associated with higher PEs. Higher social support was significantly associated with lower PEs. The results of the mediation analysis showed that social support mediated the link of FI (indirect effect: Beta = 0.06; Boot SE = 0.03; Boot CI 0.01; 0.12) and WI (indirect effect: Beta = 0.04; Boot SE = 0.02; Boot CI 0.01; 0.08) to PEs.
conclusionOur findings support the case for bolstering social support networks in war-affected communities facing survival challenges such as FI and WI. This study points to the urgent need for increased food aid and improved water supplies in the short term, and sustainable food and water systems in the long term, to support mental health. In times of war, mental health prevention and interventions strategies might do well to increase social support and resources in order to help buffer such intense environmental stressors and prevent the emergence of psychosis.
