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
backgroundIn recent years, biosynthesized nanoparticles has shown a promise as alternative avenue for improving the effectiveness of conventional chemotherapy. Despite, there is a significant gap in existing literature concerning the comprehensive study of biogenic silver nanoparticles derived from terrestrial fern species and their potential effects on cancer cells. This study is aiming to investigate effects of biogenic silver nanoparticles synthesized using aqueous extract of bracken fern Pteridium revolutum on inhibiting cell proliferation and inducing apoptosis in HCT-15 cells.
methodsBiogenic silver nanoparticles synthesized using aqueous extract of Pteridum revolutum followed by their characterization (UV-Visible spectroscopy, TEM, XRD and FTIR). The impact on cell proliferation of HCT-15 cells was assessed by MTT assay while induction of apoptosis was demonstrated via DNA fragmentation, caspase-3 assay, cell cycle arrest, FITC V- Annexin assay and evaluation of expression of apoptotic genes using real time PCR and western blotting techniques.
resultsResults of UV-Vis spectrum of colloidal solution of CW-AgNPs showed surface plasmon resonance peak at 430 nm. TEM and XRD results confirmed synthesis of spherical shaped, 20-40 nm sized nanoparticles. The results elucidate cytotoxic effect of PR-AgNPs against HCT-15 cells in time and dose dependent manner with IC50 observed at 5.79 ± 0.58 µg /mL after 24 h of exposure. Furthermore, PR-AgNPs induce significant alterations in cellular morphology, elevate DNA DNA fragmentation and enhance expression of p53 and caspase-3 in HCT10 cells.
conclusionThe findings from this study address the noteworthy antiproliferative effects of PR-AgNPs in cancer cells primarily mediated through activation of intrinsic apoptosis pathway by inducing p53 and caspase-3 genes.
