When to Choose In Vitro Fertilization (IVF) When Postponing Conceiving: The Age-Related Risk of IVF Failure at an Advanced Age.

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
Background: To validate previous age subgrouping methods and provide an optimal age reference for women planning to delay in vitro fertilization (IVF). Methods: From July 2014 to March 2018, 3012 patients that received IVF/intracytoplasmic sperm injection (ICSI) were continuously recruited in this retrospective, single-center study. We analyzed the relationships of baseline characteristics and IVF outcomes. A smooth fitting curve depicting the association of age and live birth was plotted using the generalized additive model (GAM) method. We also evaluated the association of age and live birth among different age groups (> 20, ≤ 35; > 35, ≤ 37; > 37, ≤ 40; and > 40). Results: Age, duration of infertility, and baseline follicle-stimulating hormone (FSH) were significantly related to the live birth rate. The adjusted Odd Ratio (OR) value of age was 0.95 ( Conclusion: The age of 35 can be referred to as the safe time point when the IVF success rate does not decline with age. And the risk of IVF failure increases rapidly in the period of 35-37 and 37-40.
