Analysis of HLA association among North Indian HIV-positive individuals co-infected with Mycobacterium tuberculosis.
Article in Lung India : official organ of Indian Chest Society. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundGenetic variation in HLA genes influence the immune response and may thus contribute to differential development of tuberculosis (TB) in HIV-infected individuals. The study was designed to determine whether HLA polymorphisms influence the development of Mycobacterium tuberculosis infection in HIV-infected individuals. MATERIALS AND
methodsFifty HIV-positive individuals without TB (HIV+TB-), 50 HIV patients co-infected with TB (HIV+TB+) and 50 control subjects (HIV-TB-) were analyzed for HLA Class I and II polymorphisms.
resultsIn HLA Class II, frequency of occurrence of DRB1*13 (OR 3.165, CI 1.176-8.518, P value 0.019), DRB5 (OR 2.253, CI 1.011-5.019, P value 0.045) and DQB1*06 (OR 2.705, CI 1.197-6.113, P value 0.016) were increased in HIV+TB+compared to HIV+TB-. HLA DQB1*02 (OR 0.436, CI 0.185-1.029, P value 0.05) on the other hand conferred a protective role. In HLA Class I, frequency of B*15 (OR 2.705, CI 1.040-7.036, P value 0.038) was increased, whereas B*51 (OR 0.148, CI 0.031-0.706, P value 0.007) was decreased in HIV+TB+group compared to HIV+TB-. These differences however were not significant when compared with healthy controls.
conclusionHLA polymorphisms independently did not account for the susceptibility to either of the disease mostly, although they seem to play a role once the infection(s) has established in a particular individual. Further studies are needed on a larger sample size to confirm these observations.
