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
objectivesThis study aimed to investigate the types, frequency, and longitudinal course of post-concussive symptoms (PCS) in veterans diagnosed with mild traumatic brain injury (mTBI) during the Second Nagorno-Karabakh War, with a particular focus on persistent post-concussive symptoms (PPCS) and their association with blast exposure, loss of consciousness (LOC), and alteration of consciousness (AOC).
methodsA total of 1,280 male veterans with documented mTBI diagnoses were included. Participants were divided into blast-related and non-blast groups. PCS including headache, memory impairment, dizziness, tinnitus, sleep disturbances, and irritability were tracked at six time points (from week 1 to beyond 12 months). Individuals diagnosed with posttraumatic stress disorder (PTSD) were excluded to reduce diagnostic overlap. PPCS was defined as the presence of at least one symptom persisting beyond 3 months post-injury. Generalized Estimating Equations (GEE) were used to analyze symptom trajectories, and the effects of LOC and AOC on symptom persistence were assessed.
resultsBlast exposure was significantly associated with higher early PCS rates. Symptoms such as memory impairment, dizziness, sleep disturbances, and irritability were more persistent in the blast group. AOC was more strongly associated with the development of PPCS than LOC, particularly in relation to dizziness, tinnitus, and sleep disturbances. Sleep disturbances (39.8%) and tinnitus (28.1%) were the most common persistent symptoms. LOC was not a significant predictor of long-term symptom persistence.
conclusionBlast-related mTBI, especially when accompanied by AOC, is strongly associated with persistent post-concussive symptoms, independent of PTSD. AOC emerged as a more robust predictor of delayed recovery than LOC. These findings suggest that the persistence of PCS may reflect underlying neurophysiological effects of blast injury, not merely psychological stress. Long-term monitoring and targeted rehabilitation strategies are warranted for affected individuals.
