Impact of Self-Contained Underwater Breathing Apparatus Diving on French Military Divers' Lung Function: A Retrospective Cohort.
Article in CHEST pulmonary, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Although acute risks concerning underwater divers are well documented, the literature regarding the long-term impacts on pulmonary function remains inconclusive. Although oxygen toxicity at high partial pressures is established for patients in intensive care, the impact of diving seems limited. Research Question: What are the long-term effects of self-contained underwater breathing apparatus diving on pulmonary function in military divers? Study Design and Methods: This longitudinal study used routinely collected data from Sainte-Anne Military Teaching Hospital, Toulon, France, over a 20-year follow-up period. We expressed spirometric measures as a percentage of predicted values to account for age, height, and ethnicity, and analyzed them using mixed-effects models. The impact of diving is assessed for different gas and diving apparatus. Other included variables were atopy, tobacco use, and BMI. Results: A total of 331 divers were included (2,685 spirometric measurements), with an average follow-up of 23.9 years and 2,491 dives. Only male divers met inclusion criteria. Baseline FEV Interpretation: Our results show that self-contained underwater breathing apparatus diving is associated with increased pulmonary flows and volumes in this population of military divers. Prospective studies could explore the role of unmeasured confounding factors and could significantly contribute to health policies for both military and civilian divers.
