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 association of anatomical outcomes and medications of patients with systemic diseases who underwent Descemet membrane endothelial keratoplasty with donor factors.
methodsSixty nondiabetic donors of endothelial grafts and 60 patients who underwent operation by a single surgeon were included in this retrospective study. The patients' data, including the presence of diabetes mellitus and hypertension, antidiabetic-antihypertensive medications, and intracameral tamponades and anatomical outcomes, were recorded. The donor data were obtained from eye bank records.
resultsEighteen patients had type 2 diabetes mellitus (30%) and 34 had hypertension (56.6%). Among the patients with diabetes mellitus, 13 were receiving a single-agent antidiabetic drug, 4 were receiving dual oral antidiabetic therapy, and 1 was receiving insulin therapy. Among the hypertensive patients, 11 had monotherapy and 23 had dual antihypertensive therapy. Postoperatively, 35 patients (58.3%) had an endothelial attachment, 8 (13.3%) received reinjection, 7 (11.7%) required re-Descemet membrane endothelial keratoplasty, and 10 (16.7%) underwent penetrating keratoplasty. The mean donor age was 51.2 ± 14.1 years. The most common cause of donor death was cardiopulmonary arrest (36/60 cases; 60.0%). Regression analysis revealed that the presence of diabetes mellitus significantly disrupted graft attachment (p=0.034), while the presence of hypertension, antidiabetic and antihypertensive medication use, and the type of tamponade used in the patients, and the age, sex, cause of death, and specular endothelial cell count of donors were not statistically significantly associated with graft attachment (p>0.05).
conclusionIn this study, the anatomical outcomes of Descemet membrane endothelial keratoplasty surgery were affected by recipient and donor factors. The presence of diabetes mellitus in the recipient significantly negatively affected graft attachment.
