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
backgroundRenal colic is a painful medical emergency, needs urgent intervention to reduce pain. Nonsteroidal anti-inflammatory drugs, opioids, and entonox are pain-relieving agents. This study was aimed to compare fentanyl + entonox (nitrous oxide + O MATERIALS AND
methodsOne hundred and twenty patients with acute renal colic presenting to the emergency department were enrolled. First, 50 μg fentanyl was infused for all patients. Then, patients divided into two groups receiving masks of entonox and oxygen, respectively. Quantitative measurement of pain was performed by visual analog scale, before the intervention, after 3, 5, 10, and 30 min of that. If the pain was not relieved after 30 min, 50 μg fentanyl was infused. If the pain was still continued, ketorolac and ketamine were used. Hospitalization duration and severity of pain at specified times were compared between patients in two groups.
resultsThe mean (standard deviation) time of hospitalization was 211 (59) and 236 (61) min in fentanyl + entonox and fentanyl + O
conclusionEntonox is more effective to decrease the duration of hospitalization and reduction of pain than O
