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
introductionPain, comprising sensory and emotional elements, is influenced by pain catastrophizing, which magnifies pain and promotes helplessness and rumination. This study explores the relationship between pain catastrophizing and outcomes following selective nerve root blockade (SNRB) in patients with lumbar radicular pain (LRP).
methodsA prospective cohort study of 103 LRP patients, confirmed by MRI, was conducted. All participants underwent SNRB at Umeå University Hospital. Outcomes were measured using PROMIS-29 and the Pain Catastrophizing Scale (PCS) at baseline and several intervals up to 84 days post-intervention. Patients were categorized into responder (≥30% pain reduction) and non-responder groups and stratified into three groups based on baseline PCS scores. Changes in outcomes from baseline to 14 days post-SNRB were analyzed in relation to PCS groups. PCS changes over time were evaluated between responders and non-responders. Statistical analyses assessed PCS and outcome changes.
resultsBaseline pain catastrophizing was not a significant predictor of pain response to SNRB. However, responders demonstrated significant reductions in pain catastrophizing following the intervention, suggesting that SNRB may influence cognitive coping mechanisms related to pain.
conclusionSNRB reduces pain catastrophizing in LRP patients, although baseline catastrophizing does not predict pain outcomes. Addressing catastrophizing remains important but may serve better as an outcome measure rather than a predictor of treatment response.
