The Prevalence of Early Toxoplasmosis after Bone Marrow Transplantation Using PCR: A Study in Iranian Patients.

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
backgroundIn immuno-compromised organ transplant recipients, toxoplasmosis can be caused by either an infected graft or a latent infection, during which transformation from a chronic state to an active infection (reactivation) is observed. PCR is an accurate and sensitive molecular method widely used in medical sciences, especially in diagnostic procedures.
objectiveThe aim of this study was to determine the prevalence of early toxoplasmosis infection in bone marrow transplant patients by PCR.
methodsThe blood samples of 50 patients with hematological disorders who had received bone marrow transplants were collected using a standard phlebotomy technique. To evaluate antitoxoplasma antibodies, we utilized the enzyme-linked immunosorbent assay (ELISA) method using a specific commercial kit (Akon) based on the manufacturer's instructions. Genomic DNA extracted from toxoplasma tachyzoite was used as the template for PCR.
results22 (44%) patients were women, and 28 (56%) were men. There were no significant differences in the distribution of genders and age groups in patients with various cancers. Antitoxoplasma IgG was positive in 39 patients, while none of them were IgM positive. According to PCR results, 5 patients were positive for toxoplasmosis. All of the PCR-positive cases (2 with AML, 2 with HL, and 1 with AA) had successful engraftment at 40 days post-transplantation.
conclusionBecause of the higher efficacy of PCR in the diagnosis of toxoplasmosis, using this method along with other routine diagnostic modalities in this condition is recommended. PCR-based techniques can also be utilized to periodically determine parasite load in blood after transplantation.
