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

aimsTo explore the association between plasma concentrations of brain-derived neurotrophic factor (BDNF) and the occurrence of emergence agitation (EA) in the elderly after gastrointestinal surgery.

methodsSeventy-two patients were recruited, who received gastrointestinal surgery and general anesthesia. BDNF level of blood was detected by ELISA before anesthesia (baseline), 10 min after tracheal intubation before the start of surgery, at skin closure, 10 min after tracheal extubation, and 24 h postoperatively. Patients with a Ricker Sedation-Agitation Scale (RSAS) score ≥5 at any time in the post anesthesia care unit were considered to have emergence agitation.

resultsThe incidence of EA in this population was 40 % (29/72). The EA group had higher plasma BDNF levels at skin closure (497.86 ± 69.65 vs. 307.86 ± 51.91, p < 0.05) and especially at 10 min after tracheal extubation (900 ± 224.6 vs. 476.28 ± 107.15, p < 0.001). Moreover, the levels of plasma BDNF at skin closure, 10 min after tracheal extubation and postoperative pain, were positively related with RSAS scores.

conclusionsOur results suggest that plasma BDNF is associated with the occurrence of emergence agitation after gastrointestinal surgery.
