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
Tongue swabs represent a potential alternative to sputum as a sample type for detecting pulmonary tuberculosis (TB) using molecular diagnostic tests. The methods used to process tongue swabs for testing in the WHO-recommended Xpert MTB/RIF Ultra (Xpert Ultra) assay vary greatly. We aimed to identify the optimal method for processing diagnostic tongue swabs for subsequent testing by Xpert Ultra. We compared four methods for treating dry tongue swabs with Xpert Ultra sample reagent (SR) mixed with various concentrations of Tris-EDTA-Tween (TET), to treatment with SR alone or to a commonly used SR-free heat-inactivation protocol. In each condition, swabs obtained from volunteers without TB were placed into test buffer spiked with known amounts of Importance: Xpert MTB/RIF Ultra (Xpert Ultra) is approved by the World Health Organization for the diagnosis of tuberculosis (TB). This test is typically performed using sputum specimens obtained from people with presumptive TB. In order to inactivate
