Prevalence of torque teno virus in healthy individuals and those infected with hepatitis C virus living in Yazd, Iran.
Article in Caspian journal of internal medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundTorque teno virus (TTV) is a non-enveloped DNA virus that its role as a helper or causative agent in hepatitis is still unclear. TTV prevalence varies in different regions of the world. This study aimed to determine the prevalence of TTV in healthy individuals and those infected with hepatitis C virus (HCV) living in Yazd city, Iran.
methodsIn this case-control study, 50 healthy subjects and 68 HCV-positive individuals who referred to Yazd hospitals participated in this study. TTV DNA in serum samples were detected by nested polymerase chain reaction (PCR) using specific primers of 5΄-UTR and N22 regions. The genotypes of HCV and TTV were determined by sequencing method.
resultsTTV-DNA was detected in 2 out of 50 (4℅) healthy individuals and in 4 out of 68 (5.8℅) HCV-positive persons. There was not a significant correlation between the prevalence of TTV and HCV infection. The most common TTV genotypes among HCV-positive individuals were 3, 17 and 13, respectively. There was not a significant association obtained between HCV genotypes and TTV genotypes.
conclusionThe prevalence of TTV in Yazd province was low compared with the other areas of Iran. The prevalence of TTV in HCV infected people was not significantly higher than its rate in uninfected individuals.
