Declining trend of HTLV-1 among organ/ tissue donors in Iranian Tissue Bank between 2014-2021.
Article in Retrovirology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundHuman T-cell Lymphotropic Virus type-1 (HTLV-1) infection is associated with serious disorders, including Adult T-cell Leukemia/Lymphoma (ATLL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). In addition to sexual, vertical, parenteral, and blood transfusion, organ/tissue transplantation is considered as a transmission route of HTLV infection. Given the substantial risk of HTLV-1 transmission and the subsequent development of HAM/TSP (approximately 40%) in kidney transplant recipients, pre-transplant donor screening is crucial. The present study aimed to investigate the prevalence of HTLV-1 in potential organ/tissue donors referred to the Iranian Tissue Bank and Research Center (ITBRC). MATERIALS AND
methodsThe study population was potential organ and/or tissue donors referred to ITBRC between 2014 and 2021, including two groups of brain death (potential donors of organs and/or tissues) and circulatory death donors (potential tissue donors from Iranian Legal Medicine Organization). Initial screening was performed using enzyme-linked immunosorbent assay (ELISA), and positive cases were confirmed for HTLV-1 infection with polymerase chain reaction (PCR).
results111 out of 3,814 donors were positive for HTLV-1 (3%). The rate of positive tests between 2014 and 2017 was 6%, which was significantly higher than the positive tests percentage between 2017 and 2021 with 0.5% (P-value < 0.001). The rate of test positivity in females was 4% compared to 2% in males (P-value = 0.001). Furthermore, individuals diagnosed with brain death exhibited a significantly lower likelihood of HTLV-1 infection (0.2%) compared to cases with circulatory death (4%) (P-value < 0.001).
conclusionConsidering the contraindication of organ/tissue donation from donors with HTLV-1 positive test, these findings give an insight into the prevalence of HTLV-1 among potential organ/tissue donors in Iran. Moreover, the higher prevalence of HTLV-1 infection in circulatory death donors from Iranian Legal Medicine Organization urges for cautious evaluation in these donors.
