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
Objective: The purpose of this study was to analyze the discriminative and predictive validity of the Brazilian Portuguese version of the Örebro Musculoskeletal Pain Screening Questionnaire Short-Form (ÖMPSQ-Short). Methods: In this prospective longitudinal cohort study, the ÖMPSQ-Short was administered to 150 patients with acute, subacute, and chronic nonspecific low back pain. A 6-month follow-up was also completed to assess the predictive ability of the questionnaire for risk of pain, disability, and absence from work. The Roland-Morris disability questionnaire, pain numerical rating scale, and additional questions related to work and absence from work were also used. Results: The ÖMPSQ-Short cutoff point was determined by analyzing the receiver operating characteristic curve, sensitivity, and specificity, which yielded a value of 44 points for the Brazilian population. Analysis of the 2 × 2 contingency tables showed that the ÖMPSQ-Short correctly classified high-risk patients with pain. Predictive capacity was assessed by univariate linear regression analysis. The ÖMPSQ-Short was able to predict pain, disability, and absence from work in patients with acute pain and disability in patients with subacute pain, and disability and absence from work in patients with chronic pain, but with a small predictive capacity. Conclusion: The ÖMPSQ-Short cutoff demonstrated the ability to classify patients with low and high risk of involvement of psychosocial factors. However, due to its small predictive capacity, we suggest that the ÖMPSQ-Short should not be used to predict pain, disability, and absence from work over 6 months. However, we recommend using it as a guide to discuss the patient's clinical condition.
