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

Snow mountain garlic (SMG) is a trans-Himalayan medicinal plant used in the traditional medicine system for several ailments, including inflammatory arthritis. Research studies are insufficient to validate its folk medicinal applications. In the present study, the comparative abundance of its key bioactive phytocompounds, viz., S-allyl-L-cysteine (SAC), alliin, and S-methyl-L-cysteine (SMC) against normal garlic were assessed using the LC-MS/MS-MRM method. In addition, the study also explored the antioxidant and anti-inflammatory potency of crude extract of SMG and purified signature phytocompounds (i.e., SMC, SAC, and alliin) in comparison with normal garlic and dexamethasone in LPS-stimulated RAW264.7 macrophage cells. The LC-MS/MS-MRM study revealed significant differences among SMG and normal garlic, viz., alliin 22.8-fold higher in SMG, and SMC could be detected only in SMG. In the bioassays, SMG extract and purified signature phytocompounds significantly downregulated oxidative damage in activated macrophages, boosting endogenous antioxidants' activity. SMG extract-treated macrophages significantly suppressed NF-κB expression and related inflammatory indicators such as cytokines, COX-2, iNOS, and NO. Notably, the observed anti-inflammatory and antioxidant bioactivities of SMG extract were comparable to signature phytocompounds and dexamethasone. In addition, SAC being uniformly found in SMG and normal garlic, its comparative pharmacokinetics was studied to validate the pharmacodynamic superiority of SMG over normal garlic. Significantly higher plasma concentrations (Cmax), half-life (t1/2), and area under curve (AUC) of SAC following SMG extract administration than normal garlic validated the proposed hypothesis. Thus, the abundance of bioactive phytocompounds and their better pharmacokinetics in SMG extract might be underlying its medicinal merits over normal garlic.
