1 · What the graph read from it

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.

2 · The registry

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

purposeOcular injury and vision loss are rare complications of surgery. Spine surgery has been identified as particularly high risk for postoperative vision loss; nevertheless, ocular injuries have not been comprehensively assessed in this patient population.

methodsThis historical cohort study assessed incidence, cause, and risk factors of perioperative ocular injury after spine surgery at a tertiary care medical centre from January 1, 2006 through January 31, 2018. Patients were included who had ocular injury identified during an ophthalmology consultation in the first seven postoperative days. Differences in demographic, laboratory, intraoperative, and postoperative characteristics between those experiencing or not experiencing ocular injury were assessed with Fisher exact and Wilcoxon signed-rank tests for categorical and continuous variables, respectively.

resultsOf 20,128 qualifying spine surgeries, 39 cases of perioperative ocular injuries were identified (39/20,128; 0.19% [95% confidence interval (CI), 0.14 to 0.26]). The most common ocular injury was blurry vision of unknown cause (13/39; 33%; 95% CI, 18.6 to 46.4), followed by ischemic optic neuropathy (9/39; 23%; 95% CI, 12.6 to 38.3) and corneal abrasion (7/39; 18%; 95% CI, 9.0 to 32.7). All cases of blurry vision of unknown cause were diagnosed via ophthalmology consultation and resolved within several days. Patients with perioperative ocular injury were more likely to have baseline anemia, have undergone fusion and instrumentation procedures, and had longer operative times with greater crystalloid, colloid, and transfusion requirements and more blood loss.

conclusionsAlthough not representing a causal relationship, these data suggest that surgical factors may have a greater role than demographic characteristics or other clinical factors in the development of perioperative ocular injury. Surgeons, anesthesiologists, and patients should be aware of the increased risk of ocular injury that accompanies longer, more extensive spine operations.
