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
Background and Aims: The use of intrathecal opioids is associated with high risk of pruritis and this may be decreased by adding a low dose of naloxone. This study evaluated the effect of the addition of 20 μg of naloxone to fentanyl-bupivacaine mixture on the incidence of pruritis in pregnant females scheduled for cesarean section (CS). Material and Methods: Eighty pregnant patients scheduled for CS under spinal anesthesia were randomized to receive either 10 mg of 0.5% hyperbaric bupivacaine (2 ml) plus 25 μg fentanyl (group F) or 10 mg of 0.5% hyperbaric bupivacaine (2 ml) plus 25 μg fentanyl and 20 μg naloxone (group FN). The incidence, onset, duration, site, and severity of pruritis were measured. Furthermore, the postoperative numerical rating scale (NRS) score, the total tramadol rescue analgesia, and the time for the first request of rescue analgesia were recorded. Results: Compared to the F group, the FN group showed a significant decrease in the incidence of pruritis ( Conclusions: The addition of an ultra-low dose of naloxone (20 μg) to fentanyl-bupivacaine mixture in spinal anesthesia for pregnant females scheduled for CS significantly reduced the incidence of pruritis without having a significant effect on the postoperative analgesia.
