1 · What the graph read from it

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.

2 · The registry

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

Background and Objectives: The COVID-19 pandemic and related confinement measures have exacerbated health inequalities and posed unique challenges to cognitive aging. This study examined longitudinal changes in cognitive performance and associated factors before and after the COVID-19 pandemic, using data from the Swiss Lc65+ aging study. Methods: Analyses included participants with complete data across 3 assessment waves (2016-2024): 412 participants from Cohort 1 (born 1934-1938), 702 from Cohort 2 (born 1939-1943), and 826 from Cohort 3 (born 1944-1948), with women representing 58%-63% of each cohort. Cognitive performance was measured using the Mini-Mental State Examination (MMSE). Generalized estimating equations were used to evaluate changes in cognition and associations with socioeconomic, psychological, behavioral, and nutritional indicators. Results: Significant declines in MMSE scores were observed over time in Cohorts 1 and 2 ( Discussion and Implications: Findings indicate that the COVID-19 pandemic and confinement period coincided with accelerated cognitive decline and heightened socioeconomic vulnerability among older adults, particularly in the oldest cohort. Results highlight the need for multidimensional public health strategies.
