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
Candesartan (CDN) is a useful anti-stroke medication because it lowers blood pressure, inflammation, oxidative stress, angiogenesis and apoptosis. However, CDN has limited efficacy due to its low solubility and poor bioavailability. This study set out to develop nasal pH-responsive in situ hydrogel of CDN-loaded invasomes a (PRHCLI) for enhancing CDN's release, penetration, bioavailability, and effectiveness as a possible treatment for stroke. Based on the results of the pre-formulation investigation, the optimum CLI formulation for intravasomal delivery of CDN was determined to be 3% of phospholipid, 0.16% of cholesterol, 3% of ethanol, and 1% of cineole. The optimum formulation significantly enhanced CDN permeation and release by 2.06-fold and 59.06%, respectively. The CLI formulation was added to a mixture of chitosan (0.67%w/v) and glyceryl monooleate (0.27%v/v) to develop PRHCLI. The PRHCLI formulation enhanced the release and permeation of CDN relative to free CDN by 2.15 and 2.76 folds, respectively. An experimental rat stroke model was utilized for in vivo studies to evaluate the bioavailability, effectiveness, and toxicity of the PRHCLI formulation. The nasal PRHCLI drops increased the CDN's bioavailability by 3.20-fold compared to oral free CDN. Increased grip strength and decreased flexion, spontaneous motor activity, and Morris Water Maze scores in comparison to oral free CDN showed that nasal PRHCLI drops have better anti-stroke activity. The toxicity evaluation revealed the safety of nasal PRHCLI. Hence, nasal PRHCLI drops may represent a promising avenue as a stroke therapy.
