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

Nisin is an antimicrobial polypeptide inhibitory toward Gram-positive bacterial pathogens, including Listeria monocytogenes. Encapsulating nisin in lipid nanocapsules (i.e., liposomes) has been shown to protect antimicrobial functionality in complex food matrices. The capacity of liposomes to encapsulate a fluorescent reporter was determined via spectroscopy. Survival and growth of L. monocytogenes incubated in fluid milk containing 50 IU/ml free or liposome-entrapped nisin was assayed via periodic enumeration of survivors. Liposomes were formulated from phosphatidylcholine (PC) and phosphatidyl-DL-glycerol (PG) and prepared as PC, PC/PG 7/3 or PC/PG 6/4 (mol. fraction). Antilisterial activity of nisin-loaded liposomes was determined in ultra-high temperature processed fluid milk containing approximately 4.0 log10 CFU/ml L. monocytogenes Scott A plus liposomal or free nisin at 50 IU/mL. Samples were aerobically held at 5 or 20°C; L. monocytogenes were enumerated via plating after 0, 1, 3, 6, 12, 24, 48, and 72 incubation hours. Liposome entrapment did not enhance pathogen inhibition when compared to free nisin as a function of storage temperature or incubation duration.
