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

backgroundWith the acceleration of population aging in China, the incidence of postoperative neurocognitive dysfunction (PND) will continue to rise.

aimWe aim to evaluate whether the precursor of brain-derived neurotrophic factor (proBDNF) and mature brain-derived neurotrophic factor (mBDNF) are associated with PND in elderly patients.

methodsEighty-six patients who were scheduled for elective orthopedic surgery under general anesthesia were ultimately enrolled. Referring to previous studies, the patients were divided into the PND group and the non-PND group with the Montreal Cognitive Assessment (MoCA) scale on postoperative day 7. The Spearman test was used to determine the correlations between mBDNF, proBDNF, and PND.

resultsAll the participants possessed normal cognitive function before surgery. Compared with those in the nPND group, proBDNF, mBDNF, proBDNF*mBDNF, and MoCA score (all P < 0.001) were lower in the PND group after surgery. The Spearman test showed PND was correlated with postoperative proBDNF (correlation coefficient = -0.391; P = 0.001), mBDNF (correlation coefficient = -0.295; P = 0.006), proBDNF*mBDNF (correlation coefficient = -0.479; P < 0.001), and the ratios of proBDNF (correlation coefficient = -0.388; P < 0.001) and mBDNF (correlation coefficient, -0.375; P < 0.001) from before to after surgery. DISCUSSION: In this study, PND was significantly associated with postoperative proBDNF and mBDNF; the diagnostic value of postoperative mBDNF combined with proBDNF was superior to that of either index alone.

conclusionsThe PND was significantly associated with postoperative proBDNF and mBDNF.
