U-Shaped Relationship Between Serum Lactate Dehydrogenase with All-Cause Mortality in Patients with Chronic Obstructive Pulmonary Disease.
Article in International journal of chronic obstructive pulmonary disease, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
Purpose: In the anaerobic metabolic pathway, lactate dehydrogenase (LDH) plays an important role in hypoxia, inflammation, and cell damage, making it a potential biomarker for the progression of chronic obstructive pulmonary disease (COPD). We aimed to examine the relationship between LDH levels and all-cause mortality in participants with COPD. Patients and Methods: Data of participants in the US National Health and Nutrition Examination Surveys (NHANES) 2007-2012 aged ≥20 years who underwent spirometry tests were examined, and follow-up mortality data were obtained. According to serum LDH levels, participants with COPD were divided into five groups (59-111, 112-123, 124-135, 136-150, and 151-344 U/L). To evaluate whether LDH levels were independently associated with COPD mortality, we used multivariate Cox regression analysis and smooth curve fitting. Results: We included 1320 subjects, 64 with stage III or IV COPD and 541 with stage II COPD. Over a median follow-up of 9.7 years (IQR: 7.8, 11.2), 252 of the 1320 subjects died. The mean LDH level was 132.5 U/L (standard deviation [SD], 27.0). A U-shaped relationship was observed between LDH levels and all-cause mortality. Below and above the inflection point, which was approximately 110 U/L, we found different slopes for the correlation between LDH and all-cause mortality of patients with COPD. Below the threshold, per 1-standard deviation (1SD) increase in LDH resulted in a 68% reduced risk of all-cause mortality (hazard ratio [HR] 0.32, 95% confidence interval [CI] 0.13-0.81, P=0.016); conversely, above the threshold, per 1SD increase in LDH accelerated the risk of all-cause mortality (HR 1.23, 95% CI: 1.08-1.41, P= 0.002). Conclusion: Using the nationally representative NHANES data, we found a U-shaped association between LDH level and all-cause mortality in participants with COPD. An optimal LDH level of approximately 110 U/L was associated with the lowest risk of all-cause mortality.
