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 AND
objectivesDanhong injection is the most commonly prescribed adjuvant drug applied for the treatment of cardiovascular and cerebrovascular diseases in China. Ceftriaxone is usually prescribed along with Danhong injection to elderly patients with complications. However, the pharmacokinetic interactions between these two medications have not been investigated. The aim of this study was to investigate whether Danhong injection influences the pharmacokinetic profile of ceftriaxone in old rats when these two medications are used in combination.
methodsThe animal experiment protocol was designed according to the clinical data. Ten-month-old male Sprague-Dawley (SD) rats were dosed with ceftriaxone through intravenous administration for 1 or 7 days in the presence or absence of Danhong injection. The combinations were divided into 1-day, 7-day, and 14-day combined-treatment groups in which Danhong injection was administered for 1, 7, or 14 days and ceftriaxone was given for 1, 7, or 7 days, respectively. The plasma concentration of ceftriaxone was determined by ultrahigh performance liquid chromatography coupled with triple-quadrupole mass spectrometry (UHPLC-TQ-MS) on a BEH C18 column with a mobile phase consisting of acetonitrile and 0.4% formic acid-water. The chromatographic method was validated and found to be simple, rapid, and stable.
resultsDanhong injection significantly increased the plasma clearance of and decreased systemic exposure to ceftriaxone. In the 1-day combined-treatment group, the plasma clearance of ceftriaxone increased by 52.69%, and the area under the concentration-time curve (AUC) of ceftriaxone was decreased by 32.54% (P < 0.01). In the 7-day combined-treatment group, the rate of plasma clearance increased by 52.49% and the area under the concentration-time curve decreased by 31.15% (P < 0.01). For the 14-day combined-treatment group, the plasma clearance of ceftriaxone increased by 26.73%, and the area under the concentration-time curve decreased by 21.44% (P < 0.05).
conclusionsIn old male rats, systemic exposure to ceftriaxone decreased when used concomitantly with Danhong injection, which may be because Danhong injection increased the plasma clearance of ceftriaxone. Further investigations should be carried out to clarify the mechanism for the influence of Danhong injection on the pharmacokinetics of ceftriaxone.
