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
In the present study, the effects of extraction temperature, extraction time, and ultrasonic power on extraction yield, ferric reducing antioxidant power (FRAP), total phenolic content (TPC), ABTS activities, as well as total condensed tannin (TCT) content of black pine bark extracts (PBE) were specified using the Box-Behnken experimental design. The current study also shed light on their potential anticancer, antimicrobial, antidiabetic, and anticholinesterase activities at the estimated optimal conditions. The estimated optimal conditions to achieve maximum TPC (128.00 mg GAE [gallic acid equivalent]/g of dried bark extract [dbe]), TCT (22.08 mg CE (catechin equivalents)/g of dbe), FRAP (649.49 mg TEAC (trolox equivalent antioxidant capacity)/g of dbe) and ABTS activities (802.04 mg TEAC/g of dbe) were as follows: extraction temperature of 32.52°C, extraction time of 7.43 min, and ultrasonic power of 110.68 W for PBE. Additionally, phenolic and organic compounds most commonly found in PBE were succinic acid (16.35 mg/100 g), gentisic acid (7.58 mg/100 g), and oxalic acid (6.81 mg/100 g), respectively, based on the LC-MS/MS analysis. Furthermore, PBE exhibited weak cytotoxicity across all tested cells (Caco-2, MIA PaCa-2, and HEK-293); however, its cytotoxic effects were slightly less pronounced in the healthy HEK-293 cells compared to the Caco-2 and MIA PaCa-2 cancer cells. Accordingly, PBE showed stronger antidiabetic activity than acarbose, the reference antidiabetic drug, with half-maximal inhibitory concentration (IC
