Clinical factors affecting corneal epithelial healing after epithelium-off collagen cross-linking in patients with keratoconus: a prospective cohort study.

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
purposeTo analyze the clinical factors affecting corneal epithelial healing time after epithelium-off (epi-off) corneal collagen cross-linking (CXL) in patients with keratoconus (KC).
methodsThis prospective cohort study without blinding or randomization comprised 86 patients with KC (86 eyes) who underwent epi-off CXL. The tear film breakup time (TFBUT), corneal curvature, Schirmer's test, axial length, and corneal endothelial cell count may possibly affect corneal epithelial healing were recorded and analyzed by linear regression.
resultsThe corneal epithelium healing time was 2-12 (median, 4.5) days after surgery. The group with a shorter healing time had longer TFBUT (P < 0.001), thicker thinnest corneal thickness (P < 0.01), lower grading of KC (P < 0.01), and lower corneal curvature (all P < 0.05). The healing time of the corneal epithelium demonstrated significant negative correlations with TFBUT and thinnest corneal thickness (t = - 3.686, P < 0.001 and t = - 5.044, P < 0.001, respectively). Conversely, positive correlations were observed with maximum keratometry (Kmax), simulated keratometry 2 (SimK2), and average keratometry (Kavg) (Kmax: t = 2.695, P < 0.01; simK2: t = 3. 134, P < 0.01; Kavg: t = 3.020, P < 0.01). Multiple linear regression analysis indicated that simK2 was positively correlated with corneal healing. Meanwhile, the TFBUT and thinnest corneal thickness were negative correlated with corneal epithelial reconstruction.
conclusionCorneal thickness, corneal curvature (simK2), and the TFBUT may influence epithelial healing following epi-off CXL in patients with KC. Patients exhibiting steep simK2 and thinner cornea, which may correlate with lacrimal instability, should been closely monitor corneal epithelial healing after epi-off CXL and provide treatment to promote epithelial repair.
