Protein Extraction From Mycobacterium spp. for Identification by MALDI-TOF Mass Spectrometry.
Article in Current protocols, 2026. 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
The identification of mycobacteria remains challenging due to the high species diversity within the genus and the lack of a molecular method able to identify them in a single assay. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been used as a rapid and promising alternative for bacterial identification; however, its reliability is highly dependent on effective protein extraction. This article describes a protocol specifically developed for the identification and species-level discrimination of Mycobacterium spp. that integrates thermal inactivation, multiple biomass washes, mechanical disruption with zirconia beads, protein extraction using formic acid and acetonitrile, quality control, and troubleshooting. This procedure is compatible with Bruker MALDI Biotyper systems and is designed to meet biosafety level (BSL)-2 and BSL-3 laboratory requirements, ensuring operator safety and preventing aerosol generation. Emphasis is placed on standardizing critical steps, reproducibility, and safe handling of pathogenic strains. This protocol can be applied in both diagnostic and research laboratories, offering a reliable and standardized approach to preparing mycobacterial samples for analysis by MALDI-TOF MS. © 2026 The Author(s).
