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: Nurses miss recognizingalterations in patients' conditions despite charting. This is due to a lack of knowledge and understanding of deterioration. The modified early warning score (MEWS) aids nurses in early recognition of and response to clinical deterioration. However, utilization of MEWS remains a major challenge at Mulago Hospital, where approximately 63.2% of in-hospital cardiac arrests remain unrecognized. This has resulted in a significant burden of critical illness, with a prevalence of 11.7% and mortality rate of 5.5%. Mulago Hospital-medical and surgical wards showed limited documentation of nurses' use of the MEWS. This study assessed the effect of an educational intervention on nurses' knowledge of the use of MEWS to recognize critical illnesses at the Mulago Hospital. Methods and Materials: A descriptive, quantitative, quasi-experimental one-group pretest-posttest design was employed. A convenience sample of 77 nurses from the Medical and Surgical units of Mulago National Referral Hospital participated. Nurses received face-to-face teaching on the Modified Early Warning Score (MEWS). Data were collected using a validated self-administered questionnaire, with pre-intervention data gathered two weeks before and post-intervention data one month after the training. The Wilcoxon signed-rank test was used to evaluate the effect of the intervention on nurses' knowledge of MEWS, with significance set at p < 0.05 and a 95% confidence interval. Results: The educational intervention led to a significant improvement in nurses' knowledge of the Modified Early Warning Score (MEWS), as evidenced by a Wilcoxon signed-rank test result of Z = 7.631 (p < 0.0001). Prior to the intervention, the majority of participants (67.53%, n = 52) demonstrated a novice level of MEWS knowledge. The study sample consisted predominantly of female nurses (67.53%, n = 52), with most participants (75.32%, n = 58) aged over 30 years. The mean age was 36.78 ± 8.21 years. Conclusion: Nurses' baseline knowledge of the nurses towards MEWS was low. Educational interventions significantly improved nurses' knowledge toward modified early warning scores in the recognition of critical illness.
