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

objectiveTo evaluate the effects of multimodal analgesia on postoperative opioid consumption and perioperative pain management in patients undergoing living liver donation.

methodsA retrospective study was conducted of 129 patients who underwent living liver donation between 2006 and 2015. Patients were separated into 2 cohorts, pre-multimodal analgesia and multimodal analgesia, to allow intergroup analysis. All patients received an intrathecal opioid injection and underwent donor hepatectomy. Primary outcome data compared opioid consumption in oral morphine equivalents for postoperative days (PODs) 0 to 4 between the cohorts. Secondary outcomes compared yearly averaged cumulative opioid consumption on PODs 0 to 4 in oral morphine equivalents; yearly averaged numeric rating scale pain scores; hospital length of stay; and percentage of patients receiving intravenous ketorolac, ketamine, or transversus abdominis plane blocks.

resultsFor PODs 0 to 4, a 50% reduction in overall opioids administered postoperatively (359 mg vs 179 mg;

conclusionImplementation of multimodal analgesia to manage perioperative pain in living liver donation resulted in a 50% reduction of postoperative opioid consumption. Clinically satisfactory average pain scores were maintained for PODs 0 to 4.
