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

objectivesPremenstrual syndrome (PMS) is a common cyclic psychological and somatic disorder which reduces women's quality of life. Evidence regarding the association between dietary patterns (DPs) and PMS is rare. The study aimed to determine the relationship between dietary patterns and PMS.

designThe case-control study was conducted among women with confirmed PMS and healthy individuals recruited from healthcare centres.

settingDietary data were collected using a validated semi-quantitative food frequency questionnaire and DPs were derived using principal component analysis. The association between DPs and likelihood of PMS was determined using logistic regression.

participantsIn total, 225 women with PMS and 334 healthy participants aged 20-46 years took part in the study.

resultsThree major DPs were identified: (i) 'western DP' characterized by high intake of fast foods, soft drink, and processed meats; (ii) 'traditional DP' in which eggs, tomato sauce, fruits, and red meat were highly loaded; and (iii) 'healthy DP' high in dried fruits, condiments and nuts. After taking all possible confounders into account, individuals in the highest tertile of the western DP were more likely to experience PMS (odds ratio (OR) = 1·49; 95 % CI: 1·01, 3·52), P < 0·001), whilst both healthy and traditional DP was inversely associated with the syndrome (OR = 0·31; 95 % CI: 0·17, 0·72, P = 0·02; OR = 0·33; 95 % CI: 0·14, 0·77, P = 0·01, respectively).

conclusionThe western dietary patterns were positively associated with PMS, whilst the healthy and traditional dietary patterns were inversely associated with it. Further longitudinal studies are required to confirm our findings.
