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
The goal of this study was to investigate the effects of an intermittent electrical stimulation (IES) paradigm on the healing of deep tissue pressure injury (DTPI). Electrical stimulation has been extensively studied for the treatment of open wounds, often with amplitudes lower than motor threshold. The effect of electrical stimulation in producing palpable muscle contractions on the treatment of DTPI has not been explored. IES was tested in rats with complete spinal cord injury in which a DTPI was subsequently induced. The goals of the study were to investigate: (i) the natural progression of a DTPI; and (ii) the role of IES in expediting the rate of healing. Three groups of rats were used: (a) a control group in which DTPI is induced, (b) a control group in which stimulation only is applied without the induction of DTPI and (c) an intervention group in which DTPI is induced and IES is applied. Magnetic resonance imaging monitored the extent and progression of injury 1, 3, 5 and 7 days post-induction of injury and/or initiation of IES. Immunohistochemistry assessed the severity of injury and rate of healing by evaluating the presence of inflammatory cells and embryonic myofibres. When applied on day 1 after the induction of DTPI, IES significantly reduced the edema associated with the injury, increased pro- and anti-inflammatory macrophages and increased cell proliferation. It also decreased the overall size of injury. These results suggest that when applied early after the initiation of a DTPI, IES can expedite anti-inflammatory and pro-regenerative events and may be an effective means for treating the injury.
