Psychometrics of the Lifetime Total Physical Activity Questionnaire in adults with a history of depression.

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
BackgroundDepression earlier in life is a risk factor for dementia later in life. Physical activity is associated with less risk of depression and dementia. However, prevention of Alzheimer's disease may be most effective before the onset of brain pathology, which precedes dementia symptoms by 20 + years, requiring the measure of physical activity across the life course.ObjectiveAssess the reliability and validity of the Lifetime Total Physical Activity Questionnaire (LTPAQ) in community-dwelling cognitively intact adults with and without a history of depression.MethodsTest-retest reliability was assessed with intraclass correlations (ICC). Evidence of construct validity was assessed with descriptive statistics using the contrasted group approach and a priori hypotheses testing with each intensity (sedentary, light, moderate, vigorous) within each domain (school/occupation, transportation, household, leisure-time) across the life course (school-age, adolescence, young adult, middle adult).ResultsEvidence of test-retest reliability and construct validity was found during school-age and adolescence for moderate school/occupation (ICC = 0.562,
