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

backgroundThe abductor hallucis muscle plays an important role in maintaining alignment of the first metatarsophalangeal joint. The aims of this study were (1) to determine differences in abductor hallucis muscle characteristics in people with hallux valgus between three age groups (20-44 years, 45-64 years, and 65+ years); and (2) to determine the association between age and abductor hallucis size and quality.

methodsCharacteristics of the abductor hallucis muscle were measured in 96 feet with hallux valgus using musculoskeletal ultrasound. Muscle characteristics included width, thickness, cross-sectional area and echo-intensity. A one-way ANCOVA was conducted to compare the mean muscle characteristic values between the three age groups while adjusting for hallux valgus severity as a covariate. A Bonferroni post-hoc was used to adjust for multiple testing (p < 0.0167). Spearman's rho correlation coefficient was used to determine the association between age and the abductor hallucis muscle parameters.

resultsThere was a significant difference in dorso-plantar thickness (p = 0.003) and cross-sectional area (p = 0.008) between the three age groups. The Bonferroni post hoc analysis revealed a significant difference in mean thickness and mean cross-sectional area between the 20-44 age group (p = 0.003) and the 65+ age group (p = 0.006). No significant differences were noted between the three age groups for medio-lateral width (p > 0.05) or echo-intensity (p > 0.05). Increasing age was significantly associated with a reduction in dorso-plantar thickness (r = -0.27, p = 0.008) and cross-sectional area (r = -0.24, p = 0.019) but with small effect sizes. There was no significant correlation between age and medio-lateral width (r = -0.51, p = 0.142) or echo intensity (r =0.138, p =0.179).

conclusionIncreasing age is associated with a greater reduction in size of the abductor hallucis muscle in people with hallux valgus. People over the age of 65 years old with hallux valgus display a significant reduction in abductor hallucis muscle size compared to those aged less than 45 years old. This is consistent with age-related changes to skeletal muscle.
