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

Background and Aims: Hypotension is a common adverse effect of spinal anesthesia and poses increased risks for patients with diabetes mellitus. While various tests exist for diagnosing diabetic autonomic neuropathy, dynamic pupillometry is a simple and cost-effective option. This study aimed to assess whether dynamic pupillometry can predict post-spinal hypotension in diabetic patients. Material and Methods: In this observational study, 75 patients with diabetes mellitus who were scheduled for surgery under spinal anesthesia underwent a pupillary examination the day prior. Both static and dynamic parameters were recorded. On the day of surgery, 3 ml of 0.5% hyperbaric bupivacaine was administered for spinal anesthesia, and instances of intraoperative hypotension and the use of vasopressors were noted. Results: Post-spinal hypotension occurred in 77% of the 75 patients studied, with 27 experiencing mild hypotension (20-30% drop in MAP) and 31 having severe hypotension (>30% drop). The severe hypotension group had a significantly lower baseline pupil radius (3.86 ± 0.52 mm) compared to the no hypotension group (4.37 ± 0.57 mm, Conclusions: Baseline pupil radius measured using pupillometry may serve as a simple noninvasive marker to identify diabetic patients at risk of post-spinal hypotension.
