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

purposeThe purpose of this study was to investigate whether preoperative dehydration and intraoperative hypotension were associated with postoperative acute kidney injury in patients managed surgically for kidney tumours.

methodsA retrospective analysis of 184 patients who underwent nephrectomy at a single centre was performed, investigating associations between acute kidney injury after nephrectomy, and both intraoperative hypotension and preoperative hydration/volume status. Intraoperative hypotension was defined as mean arterial pressure < 60 mmHg for ≥ 5 min. Urine conductivity was evaluated as a surrogate measure of preoperative hydration (euhydrated < 15 mS/cm; mildly dehydrated 15-20 mS/cm; dehydrated > 20 mS/cm). Multivariable logistic regression was used to evaluate associations between exposures and the primary outcome, with adjustment made for potential confounders.

resultsPatients who were dehydrated and mildly dehydrated had an increased risk of acute kidney injury (adjusted odds ratio [aOR] 4.1, 95% CI 1.3-13.5; and aOR 2.4, 95% CI 1.1-5.3, respectively) compared with euhydrated patients (p = 0.009). Surgical approach appeared to modify this effect, where dehydrated patients undergoing laparoscopic surgery were most likely to develop acute kidney injury, compared with patients managed using an open approach. Intraoperative hypotension was not associated with acute kidney injury.

conclusionPreoperative dehydration may be associated with postoperative acute kidney injury. Avoiding dehydration in the preoperative period may be advisable, and adherence to international evidence-based guidelines on preoperative fasting is recommended.
