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
backgroundToxoplasma gondii (T. gondii) infection is a common parasitic disease worldwide and has been suggested as a potential factor affecting female fertility. This study aimed to determine the seroprevalence of anti-T. gondii immunoglobulin G (IgG) and immunoglobulin M(IgM) antibodies among infertile women attending an in vitro fertilization (IVF) clinic in Mazandaran province in northern Iran and to investigate associations with demographic and clinical characteristics.
methodsA descriptive cross-sectional survey was conducted on 130 infertile women referred to the IVF department at Imam Khomeini Hospital, Sari, from 2019 to 2020. Serum samples were collected and analyzed for anti-T. gondii IgG and IgM antibodies using enzyme-linked immunosorbent assay (ELISA). Demographic and clinical data were recorded. Statistical analysis was conducted using chi-square tests and binary logistic regression to compute adjusted odds ratios (ORs) and 95% confidence intervals (CIs), aiming to identify potential factors linked to T. gondii IgG and IgM seropositivity. A P-value of less than 0.05 was considered statistically significant.
resultsAnti-T. gondii IgG antibodies were detected in 52.3% (68/130) of participants, indicating past exposure, while IgM antibodies were found in 10% (13/130). No significant associations were observed between T. gondii seropositivity and variables such as age, residence, type of infertility, history of abortion, polycystic ovary syndrome, fibroma, or previous surgeries (P> 0.05).
conclusionsThe study revealed a high seroprevalence of chronic T. gondii infection among infertile women infertile women at an IVF clinic in Mazandaran province, while only 10% showed IgM antibodies. No significant links were found between T. gondii seropositivity and various demographic or clinical factors, suggesting that the impact of T. gondii on female infertility may be less significant than previously thought. These findings suggest that while exposure to T. gondii is common in this population, it may not be a direct contributor to infertility in this context. Further research with larger sample sizes is warranted to clarify potential implications.
