Validity and reliability of a dish-based semi-quantitative food frequency questionnaire for assessment of energy and nutrient intake among Iranian adults.
Article in BMC research notes, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 21 papers, 1 of them a synthesis that pooled 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.
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
objectiveThis study aimed to assess the validity and reliability of a dish-based, semi-quantitative food frequency questionnaire (DFFQ) for epidemiological studies in Iran. The DFFQ included 142 items (84 foods and 58 mixed dishes) which was filled in by 230 adults (110 men). All participants completed two separate DFFQs with a 6 months interval as well as six 24-h recalls, each month. Dietary biomarkers and anthropometric measurements were made. The validity was evaluated by comparing the DFFQ against 24-h dietary recalls and dietary biomarkers, including serum retinol and beta-carotene. Reliability was evaluated using intra-class correlation coefficient (ICC) and validity was determined by unadjusted and energy adjusted correlation coefficients (CC), de-attenuated CC, and cross-classification analyses.
resultsICC for reliability ranged between 0.42 and 0.76. De-attenuated CC for the FFQ and the 24-h recalls ranged between 0.13 and 0.54 (Mean = 0.38). The de-attenuated CC between the DFFQ and plasma levels of retinol and beta-carotene were 0.58 (P = 0.0001) and 0.40 (P = 0.0001), respectively. Cross-classification analysis revealed that on average 73% were correctly classified into same or adjacent quartiles and 5% were classified in opposite quartiles.
