Ultrasound-guided nerve blocks for intracapsular and extracapsular hip fractures.
Trial report in The American journal of emergency medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04335461 (Postoperative Pain Control in Extracapsular Hip Fracture Patients), which is not on this map. Cited by 18 papers, 3 of them syntheses 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.

Abstract
objectivesTo compare pain relief between patients with intracapsular and extracapsular hip fractures who received an ultrasound-guided femoral nerve block (USFNB).
designA multicenter, prospective, randomized, clinical trial.
settingThe study was conducted in the emergency departments of 3 academic hospitals located in New York City. SUBJECTS: Patients aged ≥60 years presenting to the emergency department with hip fracture.
methodsA subgroup analysis from a larger data set was conducted of patients with intracapsular and extracapsular hip fractures who received an USFNB. We compared pain scores at baseline and then at 2 and 3 hours after the nerve block was performed, and also assessed pain relief at 2 and 3 hours.
resultsSeventy-seven patients were randomized to receive USFNB, of which 68 had follow-up data at 2 and 3 hours and were included in the data analysis. Thirty-one were diagnosed with intracapsular and 37 with extracapsular hip fractures. In both groups, reductions in pain scores were clinically and statistically significant. In the intracapsular group, mean pain scores decreased from 6.23 to 3.81 (P < .0001) at 2 hours and from 6.23 to 3.87 (P < .0001) at 3 hours. In the extracapsular group, mean pain scores decreased from 6.62 to 3.89 (P < .0001) at 2 hours and from 6.62 to 3.46 (P < .0001) at 3 hours. These differences were similar between the extracapsular and intracapsular groups at 2 hours (P = .92) and at 3 hours (P = .58), thus demonstrating similar reductions in pain in the 2 groups. The differences in pain relief between the intracapsular and extracapsular groups were also similar: 1.61 (confidence interval [CI], 1.14-2.08) vs 1.35 (CI, 0.96-1.75) at 2 hours (P = .39) and 1.68 (CI, 1.21-2.15) vs 1.38 (CI, 0.89-1.87) at 3 hours (P = .38).
conclusionUltrasound-guided femoral nerve block was equally effective in reducing pain for patients with both intracapsular and extracapsular hip fractures.
