Improved conservation of callus and rhizome microcuttings of Podophyllum hexandrum germplasm using the slow growth storage approach.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Podophyllum hexandrum Royle (syn. Podophyllum emodi Wall.), commonly known as Himalayan mayapple, is an endangered medicinal plant recognized as the primary natural source of podophyllotoxin, a potent compound with anticancer and antiviral properties. In this study, we developed an optimized protocol for the long-term preservation of P. hexandrum germplasm using a slow growth storage (SGS) technique, successfully preserving the viability and genetic stability of both callus and rhizome cuttings. In vitro cultured callus and rhizome microcuttings of P. hexandrum were conserved using the slow growth storage (SGS) technique in Murashige and Skoog (MS) medium under cold conditions (5 °C), supplemented with different concentrations of sucrose, mannitol, and sorbitol in combination with calcium pantothenate and spermidine, to induce slow growth and maintain tissue viability. It was observed that sorbitol (5.5%) combined with spermidine (2 mg L
