Radiological analysis of the sagittal profile of the Indian population according to the theoretical Roussouly classification.

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: Pierre Roussouly et al. classified four distinct types of sagittal profiles in normal individuals based on their sacral slope (SS). It was modified by Laouissat et al., (theoretical) including a fifth type. Study Design: The study design was a cross-sectional study. Objective: The objective of this study was to identify and classify the types of sagittal alignment present in an asymptomatic Indian population using the parameters established by Roussouly et al. and modified by Laouissat et al. Methods: The inclusion criteria were asymptomatic adults between 18 and 50 years old, without history of spinal surgery or significant musculoskeletal disorders. The sagittal profile was classified according to the Roussouly modified (theoretical) classification. The spinopelvic parameters were measured using Surgimap and the correlation analysis was performed using Pearson's correlation coefficient. Results: A total of 104 participants (62 females and 42 males) were recruited and it was observed 26 (25%) participants with Type 1, 12 (11.5%) with the Type 2, 26 (25%) with Type 3, 30 (28.8%) Type 3AP, and 10 (9.6%) participants with the Type 4. Furthermore, the study showed that the Type 3 anteverted pelvic (AP) had similar characteristics compared with the Laouissat's study. The pelvic incidence shows a correlation with SS (r = 0.602, P = 0.001) and pelvic tilt (r = 0.613, P = 0.001). SS is also correlated with lumbar lordosis (r = 0.734, P = 0.001). Conclusion: The analysis of the study showed that the Type 3 AP is the sagittal profile more frequency according to the theoretical Roussouly classification in the asymptomatic Indian population.
