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
objectiveTo identify leisure-time physical activity trajectories in older adults and examine their association with the incidence of mild cognitive impairment (MCI) over a decade.
methodsThis longitudinal study used data from the EpiFloripa Aging Cohort Study (2009-2019). The sample included older adults of both sexes, aged 60 years or older, residing in Florianópolis, Santa Catarina, Brazil. MCI was assessed using the Mini-Mental State Examination, and incidence was defined as new cases identified after baseline. Leisure-time physical activity was measured using the International Physical Activity Questionnaire. Older adults reporting no participation (≤ 10 min/week) in moderate-to-vigorous physical activity (MVPA) or walking were classified as following an 'inactive trajectory', while those maintaining ≥ 10 min/week of MVPA or walking were considered to follow an 'active trajectory'. Incidence rate ratios (IRR) and their 95% confidence intervals (95% CI) were calculated to test the associations.
resultsA total of 731 older adults were followed (66.6% women). The incidence of MCI was 104 new cases (18.5%; 95% CI: 14.8-20.9). Older adults who maintained an active trajectory of MVPA and walking in leisure time had a 40% lower risk (IRR: 0.60; 95% CI: 0.38-0.92) and a 34% lower risk (IRR: 0.76; 95% CI: 0.47-0.96), respectively, of developing MCI during the follow-up period.
conclusionMaintaining an active trajectory of physical activity was associated with a reduced risk of developing MCI after 10 years of follow-up. Leisure-time MVPA and walking programs may represent promising strategies to promote cognitive function in older adults.
