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
Introduction/Background: Workplace-based assessment (WPBA) was formally introduced into orthopedic postgraduate training in Malaysia as of December 2022. Understanding users' knowledge and perception (KAP) of WPBA is essential for ensuring its effective implementation. A systematic review is needed to evaluate whether WPBA is meeting educational expectations. Objective: This study aimed to validate a questionnaire designed to assess the knowledge and perception of WPBA among postgraduate orthopedic trainees. Materials and Methods: A pilot study was conducted from Aug 1, 2022 to May 31, 2023 involving a 28-item questionnaire that had undergone thorough face and content validation. The questionnaire was distributed to orthopedic postgraduate trainees at the Department of Orthopaedics, Traumatology and Rehabilitation, Kulliyyah of Medicine, International Islamic University Malaysia (IIUM). Rasch analysis was performed to evaluate the psychometric properties of the instrument. Results: The Rasch analysis revealed a person reliability index of 0.93 and a separation index of 3.62, while the item reliability index was 0.99 with a separation index of 8.32. The mean infit and outfit mean square (MNSQ) values were 0.99 and 0.96 respectively, with Z-standard (Z-STD) values of 0.24 and -0.35. Several misfitting items fell outside the acceptable range (0.6-1.4) and were subsequently removed from the questionnaire. Conclusions: The validation and reliability testing confirmed that the orthopedic WPBA KAP questionnaire recently developed is both reliable and valid for assessing postgraduate trainees' understanding of WPBA.
