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

introductionWith the life expectancy of patients with cystinosis increasing (ORPHA213), the corneal burden and the objective assessment of corneal crystal deposition have become increasingly important. Previous research highlights the disadvantages of hospital-prepared cysteamine solutions (HPCS), including limited efficacy, which can lead to visual decline. Cystadrops

methodsA total of 14 patients with cystinosis and corneal involvement are being followed in the multidisciplinary cystinosis clinic of the University Hospital of Leuven. Data retrieved between September 2014 and March 2023 were analyzed. All patients were initially treated with HPCS before switching to Cystadrops

resultsOCT mean crystal depth was 83% of total corneal thickness. The mean corneal density was 28.9 grayscale units. We found a positive trend (F = 0.20, p = 0.65) in corneal densitometry despite the use of HPCS, with a decreasing trend (F = 3.30, p = 0.08) after switching to Cystadrops

conclusionsThis study underscores previous research, demonstrating HPCS' limited effectiveness in reducing corneal crystal deposition due to unachievable dosing frequencies and poor stability. Our data highlights the effectiveness of Cystadrops
