Kinetics of hydrocortisone sodium phosphate penetration into the human aqueous humor after topical application.
Trial report in International journal of clinical practice, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
aim of the studyHydrocortisone is a soft steroid with low anti-inflammatory properties and a short duration of action, used to manage several ocular conditions. The clinical benefits and side effects associated with hydrocortisone are well documented, but its basic pharmacokinetic in the eye is yet to be fully elucidated. The purpose of this study is to investigate the anterior chamber penetration capabilities of hydrocortisone when used in different concentrations as eye drops treatment. MATERIALS AND
methodsThis is a double-blind, single-centre, randomised clinical trial performed at the Department of Medicine and Surgery of the University of Perugia (Italy) on consecutive patients who undergone phacoemulsification with intraocular lens implantation. Patients were randomly assigned on the morning of surgery to receive a single instillation of 0.33% (group A) or 0.001% (group B) hydrocortisone sodium phosphate solution. Group of patients C did not receive any treatment and was used to measure the hydrocortisone endogenous levels. Before surgery, one aliquot of aqueous humor for each patient was aspirated. The time of collection for each sample was recorded. Hydrocortisone concentrations were then stratified into six interval classes of 30 minutes each.
resultsThe mean concentration of hydrocortisone was significantly higher in group A (25.2 ± 12.4 ng/mL) compared with group B (7.11 ± 1.51 ng/mL) and compared with the mean hydrocortisone endogenous levels (3.92 ± 1.18 ng/mL) (P < .0001). No statistically significant differences of hydrocortisone mean concentrations between group B and the mean endogenous levels were found.
conclusionsConsidering the frequent need for prolonged topical steroid therapies and the possible consequent undesirable side effects, ophthalmologists should consider the lowest clinically effective dose of hydrocortisone useful to obtain the desired therapeutic effect and in an adequate time, to minimise the amount of steroids into the anterior chamber and to avoid side effects like intra-ocular pressure increase or cataract development.
