Peripheral T-lymphocyte subpopulations in different clinical stages of chronic HBV infection correlate with HBV load.

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
aimTo characterize the peripheral T-cell subpopulation profiles and their correlation with hepatitis B virus (HBV) replication in different clinical stages of chronic HBV infection.
methodsA total of 422 patients with chronic HBV infection were enrolled in this study. The patients were divided into three stages: immune-tolerant stage, immune active stage, and immune-inactive carrier stage. Composition of peripheral T-cell subpopulations was determined by flow cytometry. HBV markers were detected by enzyme-linked immunosorbent assay. Serum HBV DNA load was assessed by quantitative real-time polymerase chain reaction.
resultsCD8(+) T-cells were significantly higher in patients at the immune-tolerant stage than in patients at the immune-active and -inactive carrier stages (36.87 +/- 7.58 vs 34.37 +/- 9.07, 36.87 +/- 7.58 vs 28.09 +/- 5.64, P < 0.001). The peripheral blood in patients at the immune-tolerant and immune active stages contained more CD8(+) T-cells than CD4(+) T-cells (36.87 +/- 7.58 vs 30.23 +/- 6.35, 34.37 +/- 9.07 vs 30.92 +/- 7.40, P < 0.01), whereas the peripheral blood in patients at the immune-inactive carrier stage and in normal controls contained less CD8(+) T-cells than CD4(+) T-cells (28.09 +/- 5.64 vs 36.85 +/- 6.06, 24.02 +/- 4.35 vs 38.94 +/- 3.39, P < 0.01). ANOVA linear trend test showed that CD8(+) T-cells were significantly increased in patients with a high viral load (39.41 +/- 7.36, 33.83 +/- 7.50, 31.81 +/- 5.95 and 26.89 +/- 5.71, P < 0.001), while CD4(+) T-cells were significantly increased in patients with a low HBV DNA load (37.45 +/- 6.14, 33.33 +/- 5.61, 31.58 +/- 6.99 and 27.56 +/- 5.49, P < 0.001). Multiple regression analysis displayed that log copies of HBV DNA still maintained its highly significant coefficients for T-cell subpopulations, and was the strongest predictors for variations in CD3(+), CD4(+) and CD8(+) cells and CD4(+)/CD8(+) ratio after adjustment for age at HBV-infection, maternal HBV-infection status, presence of hepatitis B e antigen and HBV mutation.
conclusionDifferences in peripheral T-cell subpopulation profiles can be found in different clinical stages of chronic HBV infection. T-cell impairment is significantly associated with HBV load.
