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
backgroundCognitive impairment represents an emerging significant public health concern and a prominent risk factor for Alzheimer's disease and dementia among older adults. This study examines the association of substance use and lifestyle factors with cognitive impairment among older adults in India.
methodUtilizing data from the Longitudinal Aging Study in India (LASI) wave 1 (2017–18). We performed bivariate analyses to show association between predictors and outcome variables. Binary logistic regression was employed to understand the impact of substances use, and life style factors controlling the effect of demographic, socio-economic, and health factors on cognitive impairment.
resultsIn India, 10.76% of older adults exhibit cognitive impairment. The individual who consumed alcohol were 17% more likelihood to experience cognitive impairment (OR:1.17,95% CI:1.07,1.28). Similarly, those who smoked tobacco were 7% more likely to experience cognitive impairment (OR:1.06,95% CI:0.76,1.15). Life style also plays a significant role in determining cognitive impairment.
conclusionsSubstance use and other lifestyle factors are significantly associated with cognitive impairment among the older adults in India. Therefore, encouraging older adults who use tobacco or alcohol to assess their cognitive function at an earlier stage that could prevent or mitigate cognitive impairment, thereby enhancing their quality of life. This contribute to achieve of Sustainable Development Goals, particularly Goal 3 that guaranteeing good health and wellbeing for all.
