Management of Latent Tuberculosis Infection Based on T-SPOT.TB Assay in Patients with Hematological Malignancies.
Article in Mediterranean journal of hematology and infectious diseases, 2023. 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 and objective: Patients with latent tuberculosis infection (LTBI) receiving chemotherapy for hematological malignancy (HM) are at high risk of developing active tuberculosis (TB) infection. The aim of this study is to show real-life data and results of the T-SPOT test and preventive isoniazid (INH) therapy in pre-chemotherapy LTBI screening in the HM patient group. Methods: This retrospective study includes 209 HM patients who had T-SPOT test between 2016 and 2021 in Sultan 2. Abdulhamid Han Training and Research Hospital in Istanbul, Turkey. Results: The prevalence of LTBI was 26.8% in 209 patients (n=56). Preventive INH therapy was initiated in 82.1% (n=46) of 56 patients with LTBI. 23.9% (n=11) of the 46 patients who received preventive INH therapy were unable to complete the treatment. Nine patients died due to malignancy; one was lost to follow-up, and only one had to stop INH treatment due to elevated liver enzymes. Elevated liver enzymes occurred in 4 (8.7%) patients using INH, while gastrointestinal symptoms occurred in 3 (6.5%) patients. Active TB infection emerged in none of the T-SPOT positive or indeterminate individuals but in one HIV(+) patient in the T-SPOT negative group. The active TB infection incidence rate was 217 cases/100.000hab/year (95% CI, 29-748). Conclusions: INH treatment was generally well tolerated, and very few serious drug-related side effects were observed. Although LTBI cannot be demonstrated in patients with HIV(+) HM who are scheduled for chemotherapy, these patients should be closely monitored for the development of active TB infection.
