How I do it: simple ad-hoc pulsatile pump model for realistic microsurgical training under pulsatile flow.

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
backgroundThis simple pulsatile pump model (PPM) provides a realistic and low-cost model for microsurgical training. In this manner, the use of live animals for realistic microsurgical training is reduced, as it is possible to combine our model with several artificial microsurgical training models while retaining pulsatile flow.
methodWe detail steps for construction of the PPM for realistic microsurgical training under pulsatile flow - as well as microsurgical training examples - in a tried-and-true, cost-effective fashion, from readily available monitoring and infusion materials. The PPM is prepared by assembling a closed-loop system with two pressure applicators (infusion pumps/infusomats), a monitoring set connected to a transducer and display, and various infusion components (two intravenous drip/intrafix sets, saline, three-way stopcocks/discofix C, Heidelberger extension line, and pressure bags), allowing for adjustable pulsation frequency, flow and pressure as well as continuous pressure monitoring. The PPM can be used for a variety of microsurgical tasks, including microvascular repair and anastomosis and aneurysm clipping, providing a realistic and controlled animal-free training environment.
conclusionThis model enables near-realistic microsurgical training under adjustable pulsatile flow based on readily available materials.
