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
Background: Self-reported educational attainment is a much-used variable in research, but few studies have addressed the validity of this information. This study assesses the criterion validity of self-reported educational attainment from a telephone interview by comparing it with registry-based data from Statistics Norway. Design and methods: Self-reported educational attainment was collected from 348 persons aged 18-80 years residing in Norway as part of a dietary study involving two 24-hour recalls conducted over the telephone during the spring of 2021. Information about officially registered educational attainment from Statistics Norway was later obtained for the same participants, and information from both sources was compared for 344 participants. Results: When dividing the participants into three educational groups, 77 % were classified in agreement with the officially registered educational attainment by self-report with regard to educational attainment. Twenty percent overreported their own educational attainment, while only 3% underreported. When dividing the participants into only two educational groups according to whether they had university/college education or not, 86% were in agreement with the officially registered educational attainment, 12% overreported their educational attainment and 2% underreported. Conclusions: The majority of participants were classified in agreement with the officially registered educational attainment by self-report, but overreporting was more common than underreporting. These results should be taken into consideration when using self-reported educational attainment in research.
