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 trauma-focused psychotherapy remains the first-line treatment for posttraumatic stress disorder (PTSD), 14% to 35% of individuals with PTSD fail to achieve symptom remission. Transcranial magnetic stimulation (TMS) has shown promise as an adjunctive intervention, but its efficacy for PTSD remains inconsistent and may be better informed by the incorporation of brain-based signals to guide stimulation. To address this, we developed a connectivity-based modeling framework to identify functional networks that predict symptom severity and to estimate where stimulation would most effectively reduce PTSD symptoms. Methods: We used clinical, structural, and resting-state functional data from 350 veterans with and without PTSD. Principal component analysis (PCA) was applied to functional connectivity matrices to reduce dimensionality, and resulting component scores were entered into a least absolute shrinkage and selection operator regression to identify connections associated with symptom severity. To simulate TMS effects, we generated electric field models for 200 randomly distributed cortical sites per participant and used these distributions to estimate connectivity changes proportional to the modeled fields. The estimated changes were combined with PCA regression weights to predict stimulation-induced symptom changes at each site and were mapped across the cortex to create a whole-brain TMS targeting atlas. Results: The model identified 2 broad and opposing patterns. Stimulation expected to increase connectivity in the left prefrontal cortex was predicted to reduce symptoms, whereas stimulation expected to decrease connectivity in bilateral parietal and occipital regions was also predicted to reduce symptoms. Conclusions: These findings provide a framework for individualized TMS targeting in PTSD and generate potential therapeutic targets for future clinical trials.
