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
purposeTo evaluate the prevalence of ONFH among the military draft-eligible male population in South Korea between 2013 and 2022.
methodsA total of 3,166,669 individuals were examined at regional Military Manpower Administration offices for 10 years. In a study using a retrospective analysis of prospectively collected data, the prevalence of ONFH per 100,000 individuals, along with the 95% confidence interval (CI), was measured among military draft-eligible Korean males. The Mann-Kendall trend test was performed to assess the correlation of the ONFH prevalence with several potentially related factors.
resultsThe mean annual prevalence of ONFH was 13.04 (95% CI: 9.06-17.01), indicating a rare entity. The prevalence was nearly consistent (Tau = - 0.2; p = 0.484), with the highest in 2018 (21.54; 95% CI: 16.42-26.66) and the lowest in 2020 (10.99; 95% CI: 7.12-14.85). Unilateral ONFH had a higher proportion than bilateral ONFH. There was a significant correlation between the prevalence of ONFH and the rate of risk alcohol consumption (Tau = 0.644, p = 0.009).
conclusionThe prevalence of ONFH in military draft-eligible males was low, with nearly consistent trends between 2013 and 2022. Unilateral ONFH was relatively high compared to bilateral cases, highlighting distinctive characteristics in the military draft-eligible male population.
