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
introductionDiagnostic radiographers work in environments where ionizing radiation is used, making radiation protective measures essential for occupational safety. Personal Radiation Monitoring Devices (PRMDs) are used by diagnostic radiographers to monitor cumulative occupational exposure, resulting from faulty equipment or unsafe work practices; however, research indicates that strict adherence to PRMD use is not consistent. The study aimed to explore radiographers' knowledge, awareness and adherence to PRMD use in five major state hospitals in Namibia.
methodsA quantitative, cross-sectional and descriptive study was conducted using an online questionnaire. Fifty radiographers from five major Namibian public hospitals were targeted through convenience sampling. Data were analysed using IBM SPSS version 26 to assess levels of knowledge, awareness and adherence.
resultsThirty radiographers participated in the study with a mean age of 32 years. Most respondents, n = 23 (77%), demonstrated adequate knowledge regarding PRMDs, with n = 26 (87%) 'strongly agreeing' that they understood the purpose of PRMDs. Regarding awareness, n = 14 (47%) showed good awareness; however, n = 22 (73%) reported not knowing their cumulative radiation exposure. Access to dose results was limited, with only n = 7 (23%) regularly reviewing their readings. Additionally, n = 22 (73%) reported that they would continue working without a PRMD.
conclusionNamibian radiographers demonstrated adequate knowledge and awareness of PRMDs; however, adherence was low. It highlights the need for stricter compliance policies and enforcement. Further research is needed to investigate barriers to consistent usage and identify effective strategies to improve adherence.
