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
Introduction: The COVID-19 pandemic affected mental health worldwide. The COSMO-Spain study analyses risk perceptions, behaviours, knowledge and other pandemic related variables, such as well-being. This work aimed to assess the evolution of self-reported well-being in Spain from May 2021 to September 2022 and its association with demographic and COVID-19 related factors. Methods: An online, nationwide cross-sectional panel survey was applied in seven rounds with 1000+ participants each, with a total sample of 7266 participants, representative of the Spanish adult general population. The main variable was well-being, measured with the World Health Organization Well-Being Index (WHO-5) total score, an index with a total score from 0 to 100 (0 = worst well-being, 100 = best well-being). Other variables included in the survey were: sociodemographic data, concern about COVID-19, feelings of depression and fear, COVID-19-related worries, risk perception, self-efficacy, preventive behaviours, pandemic fatigue, health literacy, information search behaviours, and trust in several institutions. A multiple linear regression was run to analyse the associated factors with the WHO-5 total score. Results: The WHO-5 total score showed a significant increase from rounds 6 (May-June 2021) to 8 (September-October 2021). Women (standardized b coefficient (b) = -0.10), youth or people with lower socioeconomic status (worsened Conclusions: This study shows rising levels of well-being until a plateau was reached in October 2021. Vulnerable groups may be at higher risk of worsened mental health and should be addressed by policymakers. Further longitudinal studies should evaluate causality and evolution patterns of well-being throughout the COVID-19 pandemic.
