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 early- and late-stage complications of accelerated cross-linking (A-CXL) in a large case series and investigate the relationship of A-CXL complications with ocular and systemic conditions accompanying keratoconus.

methodsRetrospectively, records of 2025 eyes of 1184 patients diagnosed with keratoconus between March 2013 and 2020 who underwent A-CXL (18 mW/cm

resultsThe mean age of patients was 26.16 ± 6.05 (range 18-42), and the mean follow-up time was 3.40 ± 1.63 years (range 1-8 years). Vernal keratoconjunctivitis (3.7%) was the most common disease accompanying keratoconus. Less frequently, systemic allergic diseases (2.9%) and Down syndrome (2.3%) were observed. The most common complication in the early postoperative period was haze formation (9.1%), while failure of the treatment (4.2%) occurred in the late period. Other common complications were loss of two or more Snellen lines (2.4%) and delayed epithelial healing (1.8%). There was a significant relationship between vernal keratoconjunctivitis and delayed epithelial healing (p = 0.011). Statistically significant relationships were found between Down syndrome and haze formation (p < 0.001) and sterile infiltrate formation (p = 0.041).

conclusionAlthough A-CXL complication rates are low, vernal keratoconjunctivitis following A-CXL might increase the risk of delayed epithelial healing, and similarly corneal haze and sterile infiltrates might be observed more frequently in patients with Down syndrome.
