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
backgroundThe health sector is facing new challenges due to the impact of climate change on health. At the same time, it significantly contributes to our society's climate footprint. Hospitals producing considerable amounts of waste are an important aspect of this burden. The aim of this work was to quantify the amount of waste produced by eye surgery and, as an optimization measure, to evaluate the effect of glass separation from residual waste. MATERIAL AND
methodsOver a 2-week period, the waste generated by eye operations in the surgical theater of our university hospital was measured. Another 2‑week long measurement was conducted after the initiation of glass separation from general waste. The data obtained allowed a comparison of the two periods, the type of waste (residual and recyclable) as well as the type of operation (intraocular, extraocular). Considering regional waste disposal costs, an economic comparison was also performed.
resultsIn the first measurement period (196 operations), a total of 549.6 kg of waste was generated, 87% (478.3 kg) of which was residual waste, corresponding to 14.3 tons of total waste annually. Intraocular procedures generated on average 80% more waste than extraocular procedures: 18.1 ± 3.9 kg and 11.4 ± 4.0 kg, respectively, per day and theater. Separation of glass from residual waste reduced its quantity by 7.2% in the second measurement period (197 procedures). As the disposal of glass is free of charge in the city of Essen, this resulted in a small economic advantage (extrapolated to 112 € per year).
conclusionThe amount of waste generated by ophthalmic surgery is substantial, with a predominant proportion of non-recyclable residual waste. Intraocular operations are the cause of the majority of the waste produced. Simple measures, such as disposing of glass separately, are helpful and inexpensive to reduce the quantity of residual waste.
