1 · What the graph read from 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.

2 · The registry

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

purposeThe validity of recall of past body weight has been measured and tends to be high; however, the paucity of validation data for recall in older age is noteworthy given the need for accounting for age and disease-related weight change in prospective studies.

methodsThe Adventist Health Study-2 (AHS-2) is a prospective, questionnaire-based study (n = 96,710) that enrolled a cohort from 2002 through 2007 to investigate the role of lifestyle exposures (diet, physical activity, anthropometrics) and health on outcomes such as cancer and mortality.

resultsThe mean difference between current weight reported 26 years earlier in AHS-1 and recall of past body weight in AHS-2 was only 0.67 kg, indicating underestimation in the recall of past body weight from ages 30 to 70 years.

conclusionsMisclassification is differential across both age and adiposity, and this tendency needs to be incorporated into the interpretation of weight history and health outcome literature.
