Association of Cataract History with Dry Eye Disease Signs and Symptoms in the DREAM 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
Background: Dry eye disease (DED) and cataracts are highly prevalent ocular conditions, particularly among older adults. However, the relationship between cataracts, cataract surgery, and DED severity remains poorly understood. This study aimed to assess the associations between cataract history and DED signs and symptoms in participants with moderate-to-severe DED. Methods: This is a secondary analysis of data from a double-blind randomized control trial of participants (n = 535) with moderate-to-severe DED in the DREAM Study. At baseline, cataract history and patient characteristics were collected; DED signs and symptoms were assessed at baseline, 6 and 12 months. Cataract history was classified as: no history of cataracts, ongoing cataracts (clinically diagnosed cataracts without surgical intervention), or history of cataract surgery >6 months prior to enrollment. Associations between cataract history and DED signs and symptoms were evaluated by univariate and multivariate regression analysis. Results: Among 1070 eyes from 535 participants, 646 eyes (60%) had no history of cataracts, 244 eyes (23%) had ongoing cataracts, and 180 eyes (17%) had a history of cataract surgery >6 months prior. On univariate analysis of the combined data from baseline, 6 and 12 months, corneal staining scores were significantly worse in eyes with a history of cataract surgery than eyes with ongoing cataracts and eyes without history of cataracts (4.08 vs 3.63 vs 3.14; Conclusion: Cataract surgery was not independently associated with worse DED symptoms and signs. This indicates that exacerbations of DED severity following cataract surgery are either age-related or transient in patients with moderate-to-severe DED.
