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

objectiveThe aim of this study was to determine the effect of preoperative intravenous saline hydration on postoperative renal functions and the prevention of acute kidney injury subsequent to open-heart surgery.

methodsOur investigation was designed as a prospective, randomized, and controlled single-center trial. We included 110 patients with basal renal functions that were not disrupted and who were undergoing cardiac surgery from October to December 2020. The first group (control) had fluid restriction for 12 hours prior to surgery (n = 55), and the second group (case) was hydrated with 0.9% normal saline for 12 hours before surgery (n = 55).

resultsIn the hydration group, creatinine values dropped below the preoperative values (P = 0.008) and the glomerular filtration rate values rose above the preoperative levels (P = 0.003). The early-term mortality rates were 0% for the hydration group and 5.45% for the control group (n = 3). Besides, in the hydration group, the glomerular filtration rate values on the 30th day and 360th day after surgery increased to levels even higher than those recorded preoperatively.

conclusionsAs a result of much effort, we showed that preoperative hydration can prevent severe cardiac surgery-associated acute kidney injury and related in-hospital mortality.
