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
backgroundThe current study aims to investigate the association between dietary patterns and health-related quality of life (HRQoL) in a large Iranian adult population.
methodsThis cross-sectional study was conducted using the Tehran Lipid and Glucose Study (TLGS) data. Data from 5711 adults (53.0% female) collected by trained interviewers were analyzed. For assessments of dietary intakes and HRQoL, the 147-item semi-quantitative Food Frequency Questionnaire (FFQ) and Short-Form 12-Item Health Survey version 2 (SF-12v2) were used, respectively. The physical component summary (PCS) and mental component summary (MCS) scores of HRQoL were calculated using the appropriate scoring algorithms. Dietary patterns were identified using factor analysis. General linear models were used to assess the association between dietary patterns and HRQoL scores.
resultsTwo dietary patterns, labeled as healthy and western, were identified. In men, the median (interquartile range (IQR)) of PCS and MCS were 51.4 (47.2-55.0) and 52.2 (44.2-58.2), respectively. For women, the median (IQR) of PCS and MCS were 48.9 (42.6-53.7) and 47.7 (39.6-55.2), respectively. Significant increasing trends in MCS scores were observed in both men and women across tertiles of healthy dietary pattern. For PCS scores, a significant increasing trend was noted only in women. The Western dietary pattern was not significantly associated with either PCS or MCS in women. However, in men, a significant decreasing trend in MCS scores was observed across tertiles of the Western dietary pattern.
conclusionsThe present study suggests a more beneficial effect of healthy dietary pattern on women's HRQoL. On the other hand, in men, the healthy dietary pattern is positively associated with the mental dimension of HRQoL, whereas the Western dietary pattern is negatively linked to the mental dimension of HRQoL.
