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

purposeSalzmann's nodular degeneration (SND) is a progressive corneal disease leading to decreased vision. Surgery consists of superficial keratectomy (SK) performed with or without mitomycin C (MMC) or phototherapeutic keratectomy (PTK). This study is a summary of clinical outcomes of SND patients who underwent SK, SK + MMC, and PTK.

methodsThe study used data from the Sight Outcomes Research Collaborative (SOURCE) Data Repository. Data reviewed included patient characteristics, surgery type, and logMAR scores before and after surgery. Clinical outcomes consisted of post-operative best-corrected visual acuity and SND recurrence.

resultsThe sample consisted of 5304 patients with SND, 120 (2.26%) of whom underwent unilateral or bilateral surgeries. Surgeries consisted of 123 SK, 8 SK + MMC, and 14 PTK cases with only one instance of recurrence requiring additional surgery (SK group). Separate paired sample t-tests showed that logMAR scores significantly improved from pre-surgery to post-surgery in all groups (p < 0.05 for all three groups). In a multivariate General Estimating Equation analysis accounting for pre-surgery logMAR scores and inter-eye correlation, post-surgery logMAR scores significantly differed between surgical groups (p < 0.05) with the SK group having worse post-surgery logMAR scores (0.25) than both the SK + MMC (0.17) and PTK (0.09) groups.

conclusionPatients may benefit from MMC during SK.
