Widowhood Status and Cognitive Function in Community-Dwelling Older Adults from the Mexican Health and Aging Study (MHAS).
Article in Journal of population ageing, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
We aimed to determine the association between the duration of widowhood and cognition decline. We compared the decline observed in widowed people compared with married, single, or separated persons using the scores obtained in the cognitive assessment of memory, learning, and visual exploration by adults and older adults in Mexico. The Mexican Health and Aging Study (MHAS) provides the base for this paper. This study is an analysis of the fourth data wave (2015), except for the independent variable: marital status. Marital status was built longitudinally with information from the four surveys (2001, 2003, 2012, and 2015). The sample comprised 6898 adults aged 50 and over. Cognition was assessed with an adapted Cross-Cultural Cognitive Examination (CCCE). Confounders include sociodemographic characteristics (sex, age, schooling, self-perception of economic status, and whether the individual worked or not), multimorbidity, functionality, support networks, and psychological characteristics. Of the total sample, 4094 (59.3%) were women. The mean age was 70.86 years (SD = 7.4). The baseline of the study is 2001. In 2001, 8.7% (
