Characterization of the Pre-lens Tear Film in Hydrogel and Silicone Hydrogel Contact Lens Wear.

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
Purpose: Different contact lens (CL) materials have been associated with different behaviors of pre-lens tear film components in the short term. The purpose of this randomized crossover and double-masked study was to compare the effect of wearing hydrogel and silicone hydrogel CLs on pre-lens tear film status. Methods: Soft CL wearers were recruited and randomly fitted with a hydrogel (omafilcon A) and a silicone hydrogel (stenfilcon A) CL. Tear evaporation rate, non-invasive tear break-up time (NIBUT), tear film lipid layer thickness, and partial blink rate were measured without CLs and 30 minutes after the insertion of CLs. The outcomes were analyzed using repeated measures analysis of variance or the Friedman test. Results: Twenty-four CL wearers (6 men and 18 women) aged 23.3 Conclusion: This study demonstrated that both hydrogel and silicone hydrogel CLs disrupt the tear film by increasing tear evaporation and causing tear film instability. However, CL materials affect the pre-lens tear film status differently. Further studies with longer wearing times are required.
