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
objectivesTo analyze the pregnancy outcomes in patients with positive anti-centromere antibodies (ACA) receiving
methodsA case-control study was used to retrospectively analyze the clinical data of 3955 patients who received IVF-ET therapy and had the results of antinuclear antibody (ANA) spectrum at Zhejiang Provincial People's Hospital from June 2016 to June 2023. Patients with positive ACA and negative ACA were matched at a ratio of 1∶3 using propensity score matching. Embryo outcomes of IVF were compared between the two groups, and the impact of different fertilization methods and the use of immunosuppressants on pregnancy outcomes were analyzed using self-matching. The natural conception and disease progress were followed up for ACA-positive patients after IVF failure.
resultsThe ACA-positive patients accounted for 0.86% of all IVF patients (34/3955) and 2.51% of total ANA-positive IVF patients. Regardless of whether patients received conventional IVF (c-IVF) or intracytoplasmic sperm injection (ICSI), the ACA-positive group exhibited significant differences in oocyte maturity and fertilization compared to the ACA-negative group (both
conclusionsSerum ACA positivity may disrupt oocyte maturation and normal fertilization processes, with no improvement observed with ICSI and immunosuppressant use. However, ACA-positive patients may still achieve natural pregnancy.
