Efficacy and safety of YQFM (YiQiFuMai lyophilized injection) on acute ischemic stroke (FAST): rationale and design for a randomized, double-blind, placebo-controlled trial.
Article in BMC complementary medicine and therapies, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLow blood pressure at acute ischemic stroke onset is associated with both short- and long-term adverse outcomes. Studies have shown that YQFM (YiQiFuMai lyophilized injection) can ameliorate neurological deficits in ischemic stroke.However, all of these studies are all small-sample clinical observations lacking rigorous study design for AIS with inappropriate blood pressure.
aimsTo describe the design of the YQFM aimed at reducing the disability rate in AIS patients with inappropriate blood pressure.
methodsThis trial is a prospective, multicenter, randomized, double-blind, placebo-controlled, superiority trial aimed at evaluating the efficacy and safety of YQFM in reducing the disability rate in patients with acute hypoperfusion stroke within 90 days. We will recruit 480 patients with AIS within 48 h of symptom onset from 24 hospitals, who have large atherosclerosis, systolic pressure ≤ 155 mmHg, and an NIHSS score of 4-18. Eligible patients will be randomly assigned to receive either YQFM or 0.9% NaCl injection once daily for 10 days and will be followed up until the 90th day after stroke onset.The primary outcome will be the proportion of patients with mRS ≤ 2 at 90 days after patient recruitment. Secondary outcomes will include the proportion of early neurological deterioration at 7 days, patient self-reported outcomes and the syndrome score at 10 days, MMSE scale and BI scale at 90 days.During the trial, adverse events will be recorded. These data will be analyzed according to the predetermined statistical analysis plan.
conclusionThis study is the first randomized controlled double-blind trial to evaluate the efficacy and safety of YQFM in patients with AIS. This trial will provide evidence-based data for YQFM application in AIS with inappropriate blood pressure. CLINICAL
