Sterilization of Mycobacterium tuberculosis infected samples using methanol preserves anti-tuberculosis drugs for subsequent pharmacological testing studies.

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
Pharmacokinetic/pharmacodynamic studies of anti-tuberculosis agents in animal models of tuberculosis are hampered by the frequent necessity to perform sample bioanalysis outside the biosafety level-3 environment. Thus, each specimen has to undergo tedious and time-consuming sample sterilization procedures that may also affect drug stability. Here, we tested treatment of Mycobacterium tuberculosis (Mtb) infected samples with methanol to sterilize samples while preserving drug integrity for further pharmacokinetic/pharmacodynamic evaluations. Tissue samples harvested from Mtb infected mice were homogenized, incubated in methanol, and tested for sterility. Once sterility was confirmed, the samples were used to determine concentrations of the anti-tuberculosis drug spectinamide-1599 in lung homogenates using liquid chromatography coupled with mass spectrometry. The results demonstrate that methanol sterilizes tissue samples harvested from Mtb infected mice without altering the integrity of the drug in the tissue.
