The relationship between the orientation of the lateral decubitus position for spinal anesthesia and positioning pain in patients with a femoral neck fracture: randomized non-inferiority trial.
Article in JA clinical reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo date, no clinical studies have investigated the relationship between positioning pain and orientation of the lateral decubitus position for hip fracture surgery. The aim of the present study was to test the hypothesis that performing spinal anesthesia in the lateral decubitus position with the fracture side up or down does not affect positioning pain in patients with a femoral neck fracture.
methodsThis single-center, prospective, randomized non-inferiority trial examined 78 patients who received surgery for a femoral neck fracture under spinal anesthesia. By performing spinal anesthesia in the left lateral decubitus position in all patients, the positioning of the fracture up or down was randomized. Pain score during spinal anesthesia was evaluated objectively (0, calm; 1, facial grimacing; 2, moaning; 3, screaming; or 4, unable to proceed because of restlessness or agitation).
resultsThe data from 66 patients (fracture side down [n = 35] and up [n = 31]) were analyzed. There were no significant differences between the fracture side down and fracture side up groups regarding the percentage of patients who were assessed to have intense pain (score ≥ 3) when changing position from the supine to lateral position (13/35 [37%] vs 12/31 [39%]; 95% confidence interval [95% CI] for the difference of the percentage of patients of intense pain between the groups - 25.0 to 2.2; p = 1.000).
conclusionsThere were no significant differences in the percentage of patients experiencing severe pain between the two groups. The 95% CI exceeded the preliminarily set a margin of inferiority of 20%; thus, the present study could not demonstrate the non-inferiority of the fractured side down group in terms of pain score.
