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

Photodynamic therapy (PDT) is a promising localized strategy for the treatment of cervical cancer, ranking as the fourth most common cancer among women worldwide. The integration of photosensitizers (PSs) in localized drug delivery systems (DDSs), particularly in electrospun nanofibers, holds tremendous potential to overcome the drawbacks of their systemic administration. Exploring multilayer fibrous architectures provides a versatile therapeutic platform to design the next generation of localized DDS. In this work, localized implants for cancer treatment using PDT were developed using polyhydroxyalkanoate (PHA), chitosan (CS) and polyethylene oxide (PEO) as biopolymers and a porphyrin (Por) as PS, following two approaches: blended PHA/Por electrospun microfibers and multilayered membranes (PHA-Por/CS/PEO) produced by sequential electrospinning. The synthesized Por displayed higher cytotoxicity in light compared to dark against tumor cells. All the developed membranes were characterized regarding their morphology, wettability, absorption and fluorescence properties. PHA-Por membranes exhibited overall uniform fibrous morphologies with successful Por incorporation. Nonetheless, they presented a highly hydrophobic surface, compromising the Por release and cell-material interactions. In contrast, multilayer PHA-Por/CS/PEO membranes demonstrated enhanced hydrophilicity and enabled sustained Por release. Upon light irradiation, these membranes induced a significantly greater inhibition of HeLa cell proliferation (29.61%) compared to dark conditions (6.21%), confirming their photodynamic activity.
