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

What is already known about this topic?: Congenital clubfoot is a common musculoskeletal deformity and its prevalence varies across regions. In recent years, the overall prevalence of congenital clubfoot among perinatal infants has shown an upward trend in China. What is added by this report?: This study demonstrated a significant increasing trend in isolated congenital clubfoot after 2012, whereas non-isolated cases continued to decline in the well-recognized high-prevalence region of birth defects in northern China, highlighting the distinct temporal patterns between congenital clubfoot subtypes. What are the implications for public health practice?: Continued surveillance is needed to monitor changing patterns of congenital clubfoot subtypes and clarify factors underlying the increase in isolated congenital clubfoot.
