Hematoma block for distal radius fractures - prospective, randomized comparison of two different volumes of lidocaine.
Trial report in The Journal of international medical research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
objectiveThis study aimed to compare analgesic efficacy and safety of different volumes of lidocaine injected into a fracture hematoma (hematoma block [HB]) for reducing distal radius fractures.
methodsPatients were randomly divided into two groups. Group A included patients in whom 10 mL of 2% lidocaine was injected into the fracture site and group B included patients in whom 20 mL of 1% lidocaine was injected. The fracture was manipulated after 15 minutes and the Visual Analogue Scale (VAS) score was recorded during manipulation. Patients were followed up for approximately 1 hour and complications were recorded.
resultsTwenty patients were enrolled in the study (12 women and eight men), with a mean age of 57 years (range, 32-87 years). Demographic findings were similar between the groups. The mean VAS score of group A was 5.50 ± 3.57 and that in group B was 3.09 ± 2.33, with no significant difference between the groups.
conclusionVAS scores between HB with 20 mL of 1% lidocaine and HB with 10 mL of 2% lidocaine are not significantly different. However, our study suggests that HB with 20 mL of 1% lidocaine has a better analgesic effect than HB with 10 mL of 2% lidocaine.
