Analgesic efficacy of 7 different topical NSAIDs in panretinal photocoagulation-associated pain.
Article in BMC ophthalmology, 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
backgroundTo investigate the effects of different topical non-steroidal anti-inflammatory drugs (NSAIDs) and demographic characteristics on pain perception associated with panretinal photocoagulation.
methodsBefore panretinal photocoagulation, patients received one of seven topical NSAIDs, while the control group received artificial tears. Following panretinal photocoagulation, subjective pain was assessed using the visual analogue scale. The impact of demographic factors and NSAID type on visual analogue scale scores was statistically analysed. Demographic data were compared using the Mann-Whitney U test and NSAID groups with one-way ANOVA.
resultsThe study included 270 eyes from 270 patients. No significant differences were observed among NSAID groups regarding age, gender, diabetes duration, diabetic retinopathy type, number of intravitreal injections, panretinal photocoagulation sessions, or photocoagulation energy. In all participants, pain perception was higher in females (p < 0.001), patients aged ≤ 60 years (p < 0.001), and those with proliferative diabetic retinopathy (p < 0.001). Bromfenac (p < 0.001), indomethacin (p < 0.001), nepafenac 0.3% (p = 0.002), and diclofenac (p = 0.029) significantly reduced pain, whereas ketorolac trometamol, nepafenac 0.1%, and flurbiprofen did not. Among the effective NSAIDs, nepafenac 0.3% and diclofenac were ineffective in males, while diclofenac showed no efficacy in patients over 60 years of age or those with proliferative diabetic retinopathy. No NSAID demonstrated a significant effect in non-proliferative diabetic retinopathy patients.
conclusionsBromfenac and indomethacin demonstrate consistent analgesic efficacy in nearly all patients with panretinal photocoagulation-related pain, while nepafenac 0.3% and diclofenac are effective in a majority of cases. However, heightened panretinal photocoagulation-related pain in females, patients aged ≤ 60 years and those with proliferative diabetic retinopathy may necessitate careful consideration in these populations.
