Frequency of Hepatitis B Markers in Systemic Lupus Erythematosus Patients in Iran.
Article in Asian Pacific journal of cancer prevention : APJCP, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSystemic lupus erythematosus (SLE) is a chronic autoimmune disease. Hepatitis B virus is the causative agent for chronic, acute, cirrhosis, and hepatocellular carcinoma. SLE patients with chronic or occult hepatitis B infection undergoing immunosuppressive drugs may become reactive and develop fatal hepatitis. Therefore, this study was conducted to determine HBV markers in SLE patients before the administration of immunosuppressive drugs in Ahvaz city, Iran. MATERIALS AND
methodsThe sera of 92 SLE patients were tested for HBs Ag and anti-HBc using ELISA, HBV DNA (by Nested PCR) testes. Real-time PCR was performed for the patients with positive anti-HBc and negative HBsAg. The positive HBV DNA samples were checked for HBV genotype and HBV subtypes.
resultsAmong the 92 SLE patients, three (3.3%) were males and 89 (96.7%) females . The patients' ages ranged from 14 to 70 years [mean age of 38.9±10.1]. Three of 92 (3.26%) subjects [2/3 males and 1/89 female] were positive for HBsAg, anti-HBc Ab, and HBV DNA detected with PCR (p=0.000003)]. Five of 89 (5.61%) subjects [1 male and 4/88 females were only positive for anti-HBc and negative for HBs Ag, HBV DNA(PCR) using Real-time PCR (p=0.05). The results of the nucleotide data and phylogenetic tree showed all three HBV patients were genotype D1. The results of amino acid sequencing revealed all three HBV patients were HBV subtype ayw2.
conclusionThis study proved that 3.26% of SLE patients were positive for overt HBV infection (positive for anti-HBc, HBsAg and HBV-DNA using PCR). All the three isolated HBV were genotype D1 and subtype ayw2. The fact that 5.61% of the patients were only positive for anti-HBc characterized the occult hepatitis B infection (OBI) although further investigation is needed. To prevent HBV or OBI reactivation for SLE patients before immunosuppression treatment, HBV markers including anti-HBc, HBsAg, HBV-DNA should be implemented using PCR and Real-time PCR .
