Morphine versus oxycodone analgesia after percutaneous kidney stone surgery: a randomised double blinded study.
Trial report in Urolithiasis, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled 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.
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
According to previous studies oxycodone might have some advantages over morphine in the treatment of visceral pain. This study investigated the opioid consumption (primary outcome), pain relief and side effects (secondary outcomes) of morphine versus oxycodone after percutaneous nephrolithotomy using a method where the somatic pain component was minimized. Forty-four adult patients were studied. The patients were randomised to receive either morphine or oxycodone intravenously as postoperative pain treatment. During the first 4 h after surgery the opioid consumption, pain scores and side effects (nausea, dizziness, sedation, respiratory effects and itching) were registered. The postoperative opioid consumption varied considerably between the patients but the mean opioid consumption in the morphine and oxycodone group was comparable (18.93 mg versus 16.15 mg, P = 0.7). Nausea was significantly less frequent with morphine (P = 0.03). In this study morphine and oxycodone produced similar analgesia the first 4 h after surgery but the frequency of nausea was significantly less patient-reported with morphine. The hypothesis that oxycodone would be superior in the treatment of visceral pain after percutaneous kidney stone operation was not confirmed.
