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

Objective: Chromosomal polymorphisms (CPs), subtle variations in chromosome structure, have been previously reported in individuals with infertility, particularly among men. This systematic review and meta-analysis aim to analyze associations between CPs and pregnancy outcomes, focusing on spontaneous abortion rates. Methodology: A comprehensive literature search was conducted across three databases Medline, Google Scholar and Science Direct databases from inception to December 2023 for articles reporting the impact of CPs on selected fertilization and pregnancy outcomes among men/women/couples who had sought assisted reproductive technologies [ART; either Results: From an initial 4271 articles, 16 studies met the inclusion criteria. The analysis evaluated CPs in relation to reproductive outcomes, including abortion rates (AR), fertilization rates (FR), cleavage rates (CR), clinical pregnancy rates (CPR), and good-quality embryo rates (GQER). No significant associations were observed between CPs and AR across men, women, or couples, though high heterogeneity suggested variability in study populations. CPs were associated with a modest reduction (7%) in FR (RR 0.93, 95% CI 0.88-0.97, I2 = 67.8; P-value = 0.04), and GQER (RR 0.93, 95% CI 0.89-0.96, I2 = 17.4; P-value = 0.30), and a small but statistically significant reduction CRs (RR 0.98, 95% CI 0.97-0.99, I2 = 0.0; P-value = 0.48). Conclusions: The study highlights the influence of CPs on certain fertilization and pregnancy outcomes, particularly GQER, FR and CR, while their impact on miscarriage and clinical pregnancy outcomes remains inconclusive. Further large-scale studies are necessary to investigate further associations.
