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 assess the long-term outcome of graft insertion by taco technique through a 2.8-mm clear corneal incision in patients undergoing Descemet's stripping automated endothelial keratoplasty (DSAEK).
methodsThis is a retrospective interventional case series of 77 eyes of 75 patients who underwent DSAEK in a tertiary eye hospital. The DSAEK donor grafts were folded to an uneven 70/30 taco and held at a single point using Utrata forceps. All insertions were through a 2.8-mm clear corneal incision except the two aphakic patients requiring combined SFIOL implantation. All patients underwent a comprehensive eye examination preoperatively and were followed up to 6 years postoperatively. Visual outcomes, graft clarity, and complications of all and endothelial cell loss in 22 patients with available postop specular microscopy were analyzed.
resultsOverall, 59 (76.6%) had clear grafts until the final follow-up. Visual acuity improved in 48 (62.3%) from an average of 1.3 to 0.8 logMAR (P = 0.0001). Vision was maintained in seven and worsened in four eyes. Grafts failed in 18 (23.3%) eyes: seven (9%) were primary failures, two post rejection, four done for failed PK did not clear, four due to worsening of preexisting glaucoma, and one noncompliant failed eventually. Average endothelial cell density reduction was 26.3% (mean preop donor 2419 to postop 1779 cells/mm
conclusionOur study shows good long-term clinical outcome of DSAEK using Taco technique through a 2.8-mm clear corneal incision in a tertiary hospital.
