Comparative evaluation of QuantiFERON-TB Gold Plus for diagnosis of latent tuberculosis infection during solid organ transplantation.
Article in Korean journal of transplantation, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: The diagnosis of latent tuberculosis infection (LTBI) in solid organ transplantation (SOT) patients under lifelong immunosuppression has profound effects on preoperative and postoperative management. Interferon-gamma release assay (IGRA) is widely used to screen LTBI before or after transplantation. Methods: We evaluated the effect of posttransplantation immunosuppression on IGRA and influencing factors by measuring interval change of QuantiFERON-TB Gold Plus (QFT-Plus) between pretransplantation (pre-QFT-Plus) and posttransplantation (post-QFT-Plus) state in 20 patients who previously had reactive IGRA but not taken LTBI treatment. Results: Eleven (55%) out of 20 pre-QFT-Plus reactive patients became nonreactive state in repeated QFT-Plus (post-QFT-Plus) at 194-413 days (median, 257 days) after transplantation (discordant group). Even in persistently reactive group (concordant group), interferon-gamma (IFN-γ) levels after transplantation were decreased about 34% and 36% of their pretransplantation levels for TB1 and TB2, respectively. The only significant factors that affect interval change of QFT-Plus between pre- and post-SOT status were the concentrations of IFN-γ in pre-QFT-Plus (6.93 vs. 0.44 IU/mL in TB1 and 7.33 vs. 0.71 IU/mL in TB2). Conclusions: The reactivity of QFT-Plus is significantly compromised by immunosuppressive therapy, which increase the risk of false negative, particularly in patients with low level of IGRA reactivity. Therefore, interpretation of IGRA under immunosuppressive treatment require a caution and eventually, more sensitive tuberculosis-specific cytokine markers might be needed.
