1 · What the graph read from 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.

2 · The registry

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

objectivesTo determine the relationship between age, hamstring tightness, trunk flexibility, and lumbar lordosis angle (LLA), and examine how these variables relate independently of age. Furthermore, we identified the most significant predictor of LLA in sedentary adult females with hamstring tightness.

methodsThis cross-sectional study included 80 sedentary adult females (20-59 years old) with hamstring tightness, which was assessed using the active knee extension (AKE) and straight leg raising (SLR) tests with a universal goniometer. Trunk flexibility was assessed using the fingertip-to-floor test, and the LLA was evaluated non-radiographically using a flexicurve (flexible ruler).

resultsA significant correlation was observed between age and all examined variables (p < 0.001). Specifically, age was associated with increased fingertip-to-floor distance, suggesting reduced trunk flexibility (β = 0.756), and increased SLR (β = 0.517) and AKE (β = 0.424) angles, indicating increased hamstring tightness. Furthermore, age was the significant independent predictor (p < 0.001) of LLA.

conclusionsAge is significantly correlated with decreased flexibility and reduced lumbar lordosis angle in adult females. Among the variables examined, age was the significant independent predictor of LLA. These findings highlight the need for early detection and management of age-related musculoskeletal alterations to maintain proper spinal alignment and functional mobility.
