Raspberry Pomace as a Good Additive to Apple Freeze-Dried Fruit Bars: Biological Properties and Sensory Evaluation.

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
This study investigated the impact of adding raspberry pomace to the phenolic content and biological properties of freeze-dried apple/raspberry bars. The bars were prepared by replacing apple puree with raspberry pomace (5-50%), and their phenolic compounds were assessed using ethanol and buffer extracts. This work also explored the potential bioaccessibility of phenolic compounds in enriched bars through a simulated digestion process (digest). Antioxidant, anti-inflammatory (LOX, COX-2 inhibition), antihypertensive (ACE inhibition), and antiproliferative effects on AGS and HT-29 cancer cells were evaluated. The total polyphenol content was highest in the all bar variants post-digestion. The highest-904.26 ± 23.5 mg/100 g-was determined for the B50 sample In the enriched bars, the concentration of chlorogenic acid decreased from 6.99 ± 1.08 mg/L for BP5 to 2.75 ± 0.32 mg/L for BP50, but the ellagic acid concentration increased from 1.46 ± 0.02 mg/L for BP5 to 12.73 ± 0.09 mg/L for BP50. Among the tested extracts, the highest antioxidant and LOX, COX-2 inhibiting activity was determined for digest. The ability to neutralize free radicals increased with raspberry pomace addition from 3.63 ± 0.26 mM TE/100 g for BC to 5.58 ± 0.22 mM TE/100 g for the BP50 sample. ACE inhibition was quite similar for ethanolic and digest extracts, but much weaker for buffer extracts. The lowest EC50 value was 1.04 ± 0.03 mg/mL for the BP30 ethanolic sample. Analyzed extracts showed antiproliferative activity against both tested cell lines. The EC50 values for HT-29 cancer cells decreased from 0.354 ± 0.031 mg/mL for BC to 0.026 ± 0.006 mg/mL for the BP50 digest sample. It can be assumed that the BP30 bar best met the assumed criteria, and is optimal for both sensory quality (receiving an average score of 4.45) and health benefits.
