Effect of a single warm compress prior to ophthalmic surgery on ocular surface and intraoperative visibility: a randomised controlled study.
Trial report in BMJ open ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeWe investigated the effects of a warm compress immediately before surgery on the ocular surface and intraoperative visibility during surgery.
methodsA randomised controlled quasi-experiment at Saitama Medical University Hospital. From November 2020 to September 2021, 200 patients scheduled for endophthalmic surgery were randomly assigned to a group that received a hot compress with a spontaneously heating eye mask (HM group) or a group that received only an eye mask (control group). The eye masks were applied for 20 min from 2 hours before surgery, and before and after mask application in the non-invasive tear break-up time (NIBUT), tear meniscus height (TMH) and obstruction score of the meibomian gland (meiboscore) were evaluated. The time from wetting to dry blurring of the corneal surface (corneal blurring time, CBT) was also compared before and after the warm compress.
resultsWe enrolled 100 patients in the HM group (mean age 69.0±13.3 years) and 99 patients in the control group (mean age 69.5±16.2 years). In the control group, there were no significant changes in the NIBUT, meiboscore or TMH before and after eye mask use, whereas in the HM group, the NIBUT increased from 6.7±5.1 to 9.5±5.6 s (p<0.001), the meiboscore improved from 0.71±0.93 to 0.63±0.96 (p=0.03) and the TMH significantly improved from 0.22±0.08 to 0.24±0.08 mm (p<0.001). The CBT was longer the HM group than control group (33.5±13.4 s, 25.7±14.9 s, respectively, p=0.01).
conclusionsThe condition of the ocular surface and intraoperative visibility improved after a single warm compress. TRIAL REGISTRATION NUMBER: UMIN R000047286.
