Predictive Factors for Live Birth in Autologous in Vitro Fertilization Cycles in Women Aged 40 Years and Older.
Article in Zdravstveno varstvo, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe aim of the study was to determine predictive factors for live birth after in vitro fertilization with autologous oocytes in women ≥40 years of age.
methodsAuthors conducted a retrospective analysis of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles performed at the Department of Reproductive Medicine and Gynecologic Endocrinology, University Medical Centre Maribor, Slovenia between January 2006 and December 2015 in women aged 40 or more. The characteristics of patients and cycles were compared regarding live birth as the final outcome.
resultsA total of 1920 IVF/ICSI cycles with egg retrieval in women ≥40 years of age were performed leading to 1591 embryo transfers. The live birth rate per embryo transfer was 17.3% at 40, 11.6% at 41, 8.2% at 42, 7.9% at 43, 1.9% at 44 and 0.0% at ≥45 years of age. The multivariate logistic regression model showed that besides women's age (OR 0.66, 95% CI: 0.55-0.78), the number of previous cycles (OR 0.88, 95% CI: 0.82-0.95), number of good quality embryos on day 2 (OR 1.19, 95% CI: 1.05-1.36), number of embryos transferred (OR 1.57, 95% CI: 1.19-2.07) and day 5 embryo transfer (OR 2.21, 95% CI: 1.37-3.55) were also independent prognostic factors for live birth.
conclusionsThe chance of in vitro fertilization success in women ≥40 years of age should not be estimated only on the woman's age, but also on other predictive factors: number of previous cycles, number of good quality embryos on day 2, number of transferred embryos and blastocyst embry transfer.
