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
purposeTraction exerted on the vitreous base during vitrectomy poses a risk for retinal tears. We aimed to quantify core vitreous traction during vitrectomy using spring return and pneumatic cutters.
methodsJuvenile porcine vitreous was vacuum held in a vitreous bath while traction was measured using precision force gauge during vitrectomy. The parameters included were aspiration rate, cut-rate, cutter size, and machine types.
resultsAn empirical probabilistic model was developed. The traction was proportional to the aspiration rate but insignificantly dependent on the cut-rate. The traction probability was inversely proportional to the exponential function of the traction (p < 0.05). The traction was < 0.003 N for 99% of the time using either 23- or 25-gauge cutters.
conclusionThe tractions measured were considered similar to the causative forces of an iatrogenic retinal tear during a pars plana vitrectomy. The results provide a safety reference matrix of instrumental parameters during vitrectomy.
