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
Purpose: The aim of the study was to assess the effect of policy intervention on the physician ordering of HbA1c for the patients seen at the primary health care center in Riyadh, Saudi Arabia. Methods: The study included patients over the age of 18 for whom HbA1c tests were ordered before and after the policy restrictions were implemented at the three main Primary Health Care Centers under the Ministry of National Guard Health Affairs (MNGHA) in Riyadh, between October 2020 and August 2023. Several data management steps and restrictions were carried out to identify the patients seen before and after the intervention and controlled for the confounders. The outcome variable was inappropriate testing, and early testing was defined based on standard cutoffs of HbA1c, diabetic control, and patient history. The logistic regression analysis was used to identify predictors for early testing. Results: Among 16,290 participants, the mean age was 50 ± 16 years, with a predominance of females (66.5%). Approximately 22.3% of participants were diabetic, and the mean HbA1c level was 6.2 ± 1.55%. About 89.6% of tests were deemed inappropriate based on criteria for glycemic control, diabetic status, and duration of testing. Policy restrictions led to a 70.3% reduction in the odds of early testing (OR = 0.297, 95% CI: 0.246-0.358, p < 0.001). Each unit increase in HbA1c decreased the odds of early testing by 1.517 (OR = 0.219, 95% CI: 0.193-0.249, p < 0.001). Additionally, younger participants were more likely to undergo early testing, with odds decreasing by 3% for each additional year of age (OR = 0.970, 95% CI: 0.966-0.974, p < 0.001). Conclusion: We conclude that policy restriction alone might not be effective in reducing the burden of early testing. The early testing tendency was less in the post-intervention period. However, early testing was a common practice in both pre- and post-intervention phases. As physicians are the ones ordering the tests, deeper insight is needed from the physician's perspective.
