Development and biochemical characterization of freeze-dried guava powder fortified with Lactobacillus plantarum.
Article in Journal of food science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Guava (Psidium guajava L.) is one of the most nutrient-dense fruits, which is native to tropical and subtropical regions of the world. The processing of value-added products from guava has not been carried out on a scale similar to some other fruits, which offers an opportunity to fully exploit the potential of this fruit, such as guava-based nutraceutical food products. The objectives of the present study were to develop freeze-dried guava powders (FDGPs) from two guava varieties (white and pink) and characterize their physico-chemical and nutritional properties. FDGP was also incorporated with probiotic strains of Lactobacillus plantarum, to develop a healthy nutraceutical probiotic supplement. Functional groups assessed by Fourier transform infrared (FTIR) spectroscopy exhibited the existence of strong C-Br stretch, O-H stretch, and C = C stretch vibrations; however, scanning electron micrograms (SEMs) showed the flaky structure indicating the presence of starch, dietary fibers, and esterified groups of pectin. Significant mineral concentrations (mg/100 g) of potassi-um (323-362), magnesium (26.2-28.8), zinc (0.43-0.51), and iron (0.52-0.63) were observed in FDGPs. The FDGP samples from both guava varieties had high levels of crude fiber (43.94-46.29%), vitamin C (2.27-2.49 mg/g), and phenolic compounds (57.50-61.86 mg GAE/g) as well as significant antioxidant properties. Fortification of FDGP with L. plantarum strains produced significant results in terms of probiotic viability that was nearly maintained at 10
