Future direction of tuberculin skin test: Integration of telemedicine for test reading.

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
Objective: The Tuberculin Skin Test (TST) remains an important tool for the diagnosis of tuberculosis infection (TBI), including in patients receiving immunomodulatory therapies. However, conventional in-person TST reading requires repeated hospital visits, which may pose logistical challenges and limit accessibility to care. This study aimed to evaluate the reliability of patient self-assessment of TST reactions under real-time telemedicine supervision. Methods: This prospective observational study included 100 adult patients with an indication for TST. After purified protein derivative (PPD) administration, all participants received standardized educational materials and a uniform measurement protocol. At 72 h, patients performed self-measurement of TST induration during real-time video consultations under physician guidance. Immediately thereafter, TST measurements were repeated in the outpatient clinic by a pulmonologist for comparison. Results: A statistically significant moderate agreement was observed between patient- and physician-measured induration diameters (κ = 0.535, Conclusions: Telemedicine-supported TST assessment demonstrates acceptable reliability and may serve as a practical alternative to conventional in-person evaluation, particularly for patients with TST-negative results. This approach has the potential to reduce unnecessary hospital visits and optimize healthcare resource utilization. Further studies are warranted to better define patient subgroups that may benefit from in-person confirmation.
