Effectiveness and safety of 0.15% ganciclovir in situ ophthalmic gel for herpes simplex keratitis - a multicenter, randomized, investigator-masked, parallel group study in Chinese patients.
Trial report in Drug design, development and therapy, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
objectivesParallel comparison with 0.15% ganciclovir (GCV) ophthalmic gel to evaluate the effectiveness and safety of 0.15% GCV in situ ophthalmic gel for the treatment of herpes simplex keratitis (HSK).
methodsThis was a multicenter, randomized, investigator-masked, parallel group study. HSK patients were randomly divided into two groups, with the corresponding treatment of 0.15% GCV ophthalmic gel or 0.15% GCV in situ ophthalmic gel. Symptoms and signs were observed before administration, and 3 (±1), 7 (±1), 14 (±2), and 21 (±3) days after the administration. The clinical effective rate was considered as the primary outcome. The safety profile was evaluated by AEs, visual acuity, and ocular tolerance.
resultsThe clinical effective rate in the per-protocol (PP) dataset for the treatment group and the control group were 95.10% and 93.00%, respectively (P = 0.5282). The noninferiority test showed significant differences (P = 0.000305, P < 0.025), indicating that the tested drug was noninferior to the control. Patients in the PP dataset of both groups experienced decreases in the total scores of clinical indicators. Ocular AEs were few but similar between the two groups. There were no significant differences between patients' visions between the two groups before and after administration in the safety analysis set. In terms of drug tolerance, the rates of patients without transient blurred vision during all the visits in the treatment group were higher than those for the control group (P < 0.05). During the third and fourth visits, the rates of patients with eye itching were 4.08% and 1.22% in the treatment group, and 13.59% and 8.14% in the control group, respectively (P < 0.05). During the second visit, the rates of patients with eye irritation were 14.42% in the treatment group and 25.71% in the control group (P < 0.05).
conclusionThe 0.15% GCV in situ ophthalmic gel was effective and safe for the treatment of HSK, and was not inferior to 0.15% GCV ophthalmic gel. The 0.15% GCV in situ ophthalmic gel presented superior ocular tolerance.
