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: The Knee injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF) is a condition-specific patient-reported outcome measure that is used to evaluate patients with patellofemoral pain. Purpose: To translate the KOOS-PF into the Thai language, to make necessary adaptations to a Thai cultural context, and to assess the measurement properties of the Thai version of the KOOS-PF (TH-KOOS-PF) using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: This study was conducted between December 2021 and May 2023. Language translation of the KOOS-PF was performed according to guidelines for the cross-cultural adaptation of self-report measures. Eligible participants aged 18 to 50 years were asked to complete various patient-reported outcome measures including the TH-KOOS-PF at 3 time points: baseline, 2 weeks after baseline for test-retest reliability analysis, and 2 months after baseline for responsiveness assessment. Results: The KOOS-PF was successfully translated and culturally adapted to create the TH-KOOS-PF. A total of 86 participants (mean age, 37.0 ± 8.1 years; 59.3% female) with patellofemoral pain participated in the validation process. Construct validity of the TH-KOOS-PF was demonstrated by confirmation of all a priori hypotheses. The standardized Cronbach alpha coefficient was 0.88 (95% CI, 0.83-0.91), which indicated good internal consistency. Test-retest reliability was high, with an intraclass correlation coefficient of 0.87 (95% CI, 0.77-0.92). The TH-KOOS-PF demonstrated good responsiveness, as evidenced by all predefined hypotheses' being confirmed, and there were no floor or ceiling effects. Using an anchor-based approach, the minimal clinically important difference was 11.6 points. Conclusion: The results of this study revealed the TH-KOOS-PF to be a valid, reliable, and responsive tool for assessing Thai patients with patellofemoral pain. The TH-KOOS-PF will be useful in both clinical and research settings.
