Antioxidant status and GST gene polymorphisms in antitubercular treatment-induced hepatotoxicity patients.
Article in Hepatology international, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
introductionHepatotoxicity is a serious adverse effect of antituberculosis treatment (ATT). Glutathione S-transferase (GST) is involved in the detoxification of toxic metabolites produced as a result of ATT, increased oxidative stress and decreased antioxidant levels, and differences in the GST polymorphism may be one of the causes of ATT-induced hepatotoxicity.
aimThis study was undertaken to study the relationship among antioxidant status, oxidative stress and GST gene polymorphisms in the development of ATT-induced hepatotoxicity in Indian patients. METHODOLOGY: Two hundred fifty TB patients attending clinics in the Gastroenterology and Thoracic Department, PGIMER, Chandigarh, were enrolled. Liver marker enzymes, markers of oxidative stress, levels of antioxidants and identification of GSTT1, GSTM1 and GSTP polymorphisms were performed using standard protocols.
resultsOf the 250 patients, 160 were males. Of the 160 males, 18 (11.3 %) had ATT-induced hepatotoxicity and 142 no hepatotoxicity, while of 90 females, 12 (13.3 %) had hepatotoxicity and 78 no hepatotoxicity. Patients who developed ATT-induced hepatotoxicity had significantly higher oxidative stress compared to those who did not develop hepatotoxicity at between 1 and 2 months of treatment. Among antioxidants, catalase did not show any significant difference at 2 and 4 months of treatment. The presence of GSTM1 was higher in hepatotoxicity patients as compared to non-hepatotoxicity patients, while GSTT1 and GST1/M1 were lower.
conclusionTherefore, in this study, the possible association of oxidative stress with ATT-induced hepatotoxicity was observed. A role of the GST polymorphism in ATT-induced hepatotoxicity was also found and thus could possibly identify the groups at highest risk of developing ATT-induced hepatotoxicity.
