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: Operational efficiency in outpatient pharmacies is a critical factor in healthcare delivery, directly impacting patient satisfaction and adherence to prescribed treatments. Prolonged waiting times in pharmacies can lead to patient dissatisfaction, reduced medication adherence, and potential health risks. Objective: This study aimed to analyze the impact of a data-driven intervention on reducing patient waiting times in an outpatient pharmacy at a tertiary hospital, with a goal of ensuring that patients are served within 30 min of ticket issuance. Methods: The study utilized data from the "Qsmart" ticketing system, covering October 2022 to November 2023. A descriptive analysis was conducted to identify peak service hours and assess staffing patterns. An interrupted time series analysis (ITSA) was employed to evaluate the effectiveness of an intervention implemented between January 22 and February 26, 2023. The intervention included increased staffing during peak hours, adjustments to break schedules, and enhanced pre-peak hour preparations. Results: The descriptive analysis revealed peak service hours between 9 AM and 11 AM, with the highest number of tickets issued at 10 AM. The intervention produced a significant immediate level reduction in waiting times of 0.1540 (95 %CI: 0.0421,0.2659) but there was Conclusion: The data-driven intervention effectively reduced waiting times in the outpatient pharmacy, with significant immediate improvements observed. This study highlights the potential of strategic operational adjustments to enhance service efficiency and patient satisfaction. Further research is needed to validate the sustainability and generalizability of these findings in other settings.
