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
BACKGROUND/
aimThe adverse side effects associated with chemotherapeutic agents have prompted the exploration of natural compounds as adjuvants to chemotherapy, offering more effective therapeutic alternatives. Licoricidin, a bioactive constituent of licorice, possesses diverse pharmacological properties. However, the antitumor mechanisms underlying the therapeutic effects of Licoricidin combined with paclitaxel in cervical cancer remain unclear and further investigations are warranted. MATERIALS AND
methodsCell growth and apoptosis were assessed using the MTT assay and Annexin V/PI staining. Endoplasmic reticulum (ER) stress was evaluated using the ER-ID assay. The expression of apoptosis- and ER stress-related proteins in response to the combined treatment was analyzed using western blotting.
resultsCombined treatment with licoricidin and paclitaxel effectively inhibited cell growth and induced apoptosis in human HeLa and C-33A cells. We further revealed that this combined treatment increased the expression of apoptotic proteins (c-PARP, Bax, and DR5) while decreasing the expression of pro-caspase proteins (pro-caspase-3 and pro-caspase-9) in HeLa cells. In addition, the combined treatment induced ER stress, as evidenced by decreased expression levels of ERp44, ERp57, and ERp72, whereas the expression of GRP78 was increased in HeLa cells.
conclusionThe combination of licoricidin and paclitaxel induced ER stress-mediated apoptosis and may serve as a potential antitumor therapeutic strategy against human cervical cancer cells.
