Article in Fertility and sterility, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00011713 (Human Exposure to Bisphenol A, Phthalates and Fertility, Pregnancy Outcomes.), which is not on this map. Cited by 29 papers, 3 of them syntheses that pooled it.

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.

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.

Abstract

objectiveTo evaluate the relationship between pretreatment intake of whole grains and outcomes of IVF.

designProspective cohort study.

settingAcademic medical center. PATIENT(S): A total of 273 women who collectively underwent 438 IVF cycles. INTERVENTION(S): Whole grain intake was assessed with a validated food frequency questionnaire at enrollment. MAIN OUTCOME MEASURE(S): Intermediate and clinical end points of IVF were abstracted from medical records. RESULT(S): Women had a median whole grain intake of 34.2 g per day (∼1.2 servings/day). Higher pretreatment whole grain intake was associated with higher probability of implantation and live birth. The adjusted percentage of cycles resulting in live birth for women in the highest quartile of whole grain intake (>52.4 g/day) was 53% (95% confidence interval [CI] 41%, 65%) compared with 35% (95% CI 25%, 46%) for women in the lowest quartile (<21.4 g/day). This association was largely driven by intake of bran as opposed to germ. When intermediate end points of IVF were examined, only endometrial thickness on the day of ET was associated with whole grain intake. A 28-g per day (∼1 serving/day) increase in whole grain intake was associated with a 0.4-mm (95% CI 0.1, 0.7 mm) increase in endometrial thickness. CONCLUSION(S): Higher pretreatment whole grain intake was related to higher probability of live birth among women undergoing IVF. The higher probability of live birth may result from increased endometrial thickness on the day of ET and improved embryo receptivity manifested in a higher probability of implantation.
