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

objectiveTo examine the association between ambient temperature and antral follicle count (AFC), a standard measure of ovarian reserve.

designProspective cohort study.

settingFertility center at an academic hospital in the northeastern United States. PATIENT(S): 631 women attending the Massachusetts General Hospital Fertility Center (2005-2015) who participated in the Environment and Reproductive Health Study. INTERVENTION(S): Daily temperature at the women's residential address was estimated for the 90 days before their antral follicle scan using a spatially refined gridded climate data set. We evaluated the associations between temperature and AFC using Poisson regression with robust standard errors, adjusting for relative humidity, fine particulate matter exposure, age, education, smoking status, year and month of AFC, and diagnosis of diminished ovarian reserve and ovulation disorders. MAIN OUTCOME MEASURE(S): Antral follicle count as measured with transvaginal ultrasonography. RESULT(S): A 1°C increase in average maximum temperature during the 90 days before ovarian reserve testing was associated with a -1.6% (95% confidence interval [CI], -2.8, -0.4) lower AFC. Associations remained negative, but were attenuated, for average maximum temperature exposure in the 30 days (-0.9%, 95% CI, -1.8, 0.1) and 14 days (-0.8%, 95% CI, -1.6, 0.0) before AFC. The negative association between average maximum temperature and AFC was stronger in November through June than during the summer months, suggesting that timing of heat exposure and acclimatization to heat may be important factors to consider in future research. CONCLUSION(S): Exposure to higher temperatures was associated with lower ovarian reserve. These results raise concern that rising ambient temperatures worldwide may result in accelerated reproductive aging among women.
