1 · What the graph read from 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.

2 · The registry

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

purposeTo evaluate the long-term outcomes of primary filtering surgery, including trabeculectomy and combined trabeculotrabeculectomy (CTT), in secondary childhood glaucoma (SCG) patients. STUDY

designRetrospective cohort study.

methodsSCG patients, who underwent primary filtering surgery at two tertiary hospitals between 2008 and 2018, were reviewed. Surgical success was defined as an intraocular pressure (IOP) between 5 to 21 mmHg. Failure was defined as IOP outside those criteria for two consecutive visits, the need for additional surgery, or loss of light perception. Surgical success was evaluated using the Kaplan-Meier method.

resultsSixty-four eyes (50 patients) were included. Glaucoma associated with non-acquired ocular anomalies (SCG-O) included 31 eyes from 23 patients. Median age and follow-up time were 63.6 and 18 months, respectively. Overall success probabilities were 57.8% at 1 year, 55.1% at 3 years, and 50.1% at 5 years. For trabeculectomy (55 eyes), the success probabilities were 59.5% at 1 and 3 years, and 52.0 % at 5 years. For CTT (9 eyes), the success probabilities were 44.4% at 1 year, decreasing to 33.3% at 3 and 5 years. There was no statistically significant difference between trabeculectomy and CTT. Hypotony was the most common early complication. Two eyes developed phthisis bulbi.

conclusionsPrimary filtering surgery in SCG patients showed a significant drop in the success rate to about 60% within the first year, followed by a slight decline thereafter, with a long-term success rate around 50%.
