1 · What the graph read from it

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.

2 · The registry

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 mycobacterial cell envelope plays both infectious and protective roles. Understanding its structure is crucial for unlocking the molecular basis underlying these functions. Studying glycans, the primary components of the cell envelope, is challenging due to their limited native functional handles for chemoselective modification. New labeling methods exploit biorthogonal chemistry, using small molecule mimics that intercept cellular metabolism or late-stage glycan biosynthesis. However, these strategies can have practical limitations, including probe delivery and effectiveness. An ideal small molecule probe should be easily deployed and exploit the critical enzyme-substrate relationships of natural substrates. To this end, we developed a "probegenic" strategy to label mycobacteria. Our approach eliminates the need for explicit substrate mimicry, as the relevant functionality is revealed by a target enzyme. Specifically, we synthesized an azide-substituted
