Comparison of ultrasonographic anatomy of spine in traditional sitting position versus crossed leg position in term pregnancy: A prospective, observational, crossover study.
Article in Indian journal of anaesthesia, 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
Background and Aims: The traditional sitting position (TSP) and crossed leg sitting position (CLSP) are positions used for neuraxial anaesthesia. This study compared the interspinous space (ISS) distance using ultrasound assessment of the spine in these positions in parturients in term gestation. Methods: This prospective, observational study involved ultrasonographic spine assessment in 100 parturients in term gestation with them in either TSP or CLSP. The median sagittal view measured the crescent-shaped hyperechoic reflections of the spinous processes and ISSs in L3-L4, L4-L5 and L5-S1 levels. The paramedian sagittal oblique view showed interlaminar spaces (ILSs). Paired Results: The ISS distance (cm) increased in CLSP compared to TSP at levels L3-L4 (1.44 [0.34] [1.34-1.54] versus 1.22 [0.30] [1.12-1.32], Conclusion: Crossed leg sitting position for neuraxial anaesthesia in term pregnancy results in more widening of both interspinous and interlaminar spaces compared to traditional sitting position.
