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

purposeCurrent knowledge about the ovarian reserve in patients with type 1 diabetes is inconsistent and based on studies with small sample size. This meta-analysis aimed to produce a comprehensive evaluation on the ovarian reserve of type 1 diabetes female patients and to analyze the associated factors with the ovarian reserve.

methodsSystematic searches were conducted for studies published from the inception to December 2021. Original human observational studies either with case-control, cross-sectional, or longitudinal design evaluating ovarian reserve markers between type 1 diabetes patients and healthy controls were included. Levels of anti-müllerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol (E2) were extracted.

resultsIt was indicated that women with type 1 diabetes were associated with decreased levels of AMH compared with healthy controls (weighted mean difference [WMD] -0.70 ng/ml, 95% confidence intervals [CI] -1.05 to -0.34 ng/ml, P = 0.0001). Subgroup analyses stratified by age showed that adult patients with type 1 diabetes were associated with decreased levels of AMH (WMD -0.70 ng/ml, 95% CI -1.06 to -0.34 ng/ml, P = 0.0001) and FSH (WMD -1.07 IU/L, 95% CI -1.75 to -0.39 IU/L, P = 0.002) compared with healthy controls. Meta-regression analysis showed no significant correlation between AMH, FSH, and clinical factors, while level of E2 was negatively correlated with daily insulin doses and glycosylated hemoglobin A1c (HbA1c) values.

conclusionAccording to this meta-analysis, type 1 diabetes might be associated with decreased AMH levels. Further studies using different markers and fertility outcomes focus on the ovarian reserve of women with type 1 diabetes are urgently needed.
