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

Alpha klotho (known as klotho) is a multifunctional protein that may be linked to age-associated decline in tissue homeostasis. The original klotho hypomorphic (klotho (hm) ) mouse, produced on a mixed C57BL/6 and C3H background, is short lived and exhibits extensive aging-like deterioration of several body systems. Differently, klotho (hm) mice on a pure C57BL/6 background do not appear sickly nor die young, which has permitted us to gain insight into the effect of klotho deficiency in adult life. First, analyzing klotho transcript levels in the kidney, the main site of klotho production, we demonstrated a 71-fold decline in klotho (hm) females compared to wildtype females versus only a 4-fold decline in mutant males. We then examined the effect of klotho deficiency on muscle-related attributes in adult mice, focusing on 7-11 month old females. Body weight and forelimb grip strength were significantly reduced in klotho (hm) mice compared to wildtype and klotho overexpressing mice. The female mice were also subjected to voluntary wheel running for a period of 6 days. Running endurance was markedly reduced in klotho (hm) mice, which exhibited a sporadic running pattern that may be characteristic of repeated bouts of exhaustions. When actually running, klotho (hm) females ran at the same speed as wildtype and klotho overexpressing mice, but spent about 65 % less time running compared to the other two groups. Our novel results suggest an important link between klotho deficiency and muscle performance. This study provides a foundation for further research on klotho involvement as a potential inhibitor of age-associated muscle deterioration.
