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
purposeThe aim of this study was to investigate the influence of preoperative dry eye disease (DED) and ascorbic acid (AA) status on the outcomes of kerato-lenticule extraction (KLEx) surgery. The postoperative outcomes included visual and refractive parameters.
methodA prospective, non-randomized controlled trial was conducted, and 68 patients who received KLEx surgery were included. These patients were divided according to their DED status and AA level, and a total number of 33, 19, and 16 patients/eyes were classified into non-DED, DED-high AA, and DED-low AA groups, respectively. The uncorrected distance visual acuity (UDVA), cycloplegia refraction, and AA concentration were determined before and after surgery. The Kruskal-Wallis test was used to investigate the postoperative outcomes among the three groups.
resultsOne week postoperatively, the three groups presented similar UDVA and refraction values (all P > 0.05). One month postoperatively, however, the DED-low AA group demonstrated worse UDVA than the non-DED and DED-high AA groups (P = 0.012). After the KLEx surgery, the DED-low AA group still had the lowest AA level compared with the other two groups (both P < 0.05), and the decrease in AA was the largest in the DED-low AA group compared with the other two groups (both P < 0.05). High myopia was related to worse postoperative UDVA in the DED-high AA group (P = 0.034), and high myopia and large optic zone (OZ) were significantly correlated with worse postoperative UDVA in the DED-low AA group (both P < 0.05).
conclusionThe concurrent presence of DED and a low baseline AA status was correlated with worse postoperative UDVA in patients who received KLEx surgery. Additionally, this population had more risk factors for poor postoperative UDVA than the other populations.
