Developing a brief older adults' physical activity questionnaire.

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
aimThis study aimed to develop and evaluate the Brief Older Adults' Physical Activity Questionnaire (BOPAQ), which was designed to quickly assess moderate-to-vigorous physical activity (MVPA) in community-dwelling older adults.
methodsWe used a cross-sectional study design involving 165 older participants. The BOPAQ calculated weekly MVPA duration based on two questions regarding the number of days per week engaged in MVPA and the daily duration of activity. Validity was assessed by correlating the MVPA durations derived from the BOPAQ with those obtained from the ActiGraph and International Physical Activity Questionnaire short form. Reliability was evaluated using the intraclass correlation coefficient, and measurement errors were analyzed using Bland-Altman plots.
resultsThe BOPAQ reasonably correlated with accelerometer-based MVPA (rho = 0.297) and showed good test-retest reliability (intraclass correlation coefficient of 0.78, 95% CI 0.64-0.87). In contrast, the correlation between the International Physical Activity Questionnaire short form and accelerometer-based MVPA was poor (rho = 0.139). The cut-off value for the BOPAQ was set to identify participants engaging in <150 min of objectively measured physical activity per week, corresponding to the 150-min threshold. However, the area under the curve in the receiver operating characteristic analyses was not significantly high (0.601, 95% CI 0.514-0.688). The Bland-Altman plots showed an underestimation bias of 51.72 min/week (95% CI 1.61-101.84) and showed heteroscedasticity.
conclusionDespite some measurement errors, the BOPAQ is an available tool for assessing MVPA in community-dwelling older adults. Geriatr Gerontol Int 2024; 24: 1150-1155.
