Safety, Tolerability, and Serum/Tear Pharmacokinetics of Human Recombinant Epidermal Growth Factor Eyedrops in Healthy Subjects.

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
The purpose of this study was to evaluate the safety, tolerability, and pharmacokinetics (PKs) of rhEGF eyedrops after the administration of single and multiple doses in healthy subjects. A phase 1, randomized, double-blind, placebo-controlled, and single-ascending dose (SAD) and multiple-ascending dose (MAD) study were conducted in three dose groups (10, 50, and 100 μg/mL). The subjects randomly received rhEGF eyedrops or the placebo in a 3:1 ratio. Serial blood and tear samples for PK analysis were collected up to 36 h and 180 h post-dose in SAD and MAD studies, respectively. In addition, the serum and tear EGF concentrations were measured. Immunogenicity evaluations were conducted using serum anti-EGF antibody levels. A total of 50 subjects were enrolled and 48 subjects completed the study. Adverse drug reactions were mild and transient. There were no serious adverse events in this study. The tear EGF concentrations rapidly increased and returned to baseline after 4 h without any serum EGF level change after the administration of rhEGF eyedrops. rhEGF eyedrops were safe and well-tolerated in healthy subjects in a dose range of 10-100 μg/mL, indicating suitability for further studies in patients with corneal injury.
