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
backgroundDelays in diagnostic colonoscopy after abnormal stool-based colorectal cancer screening are common in health-disparity populations and are associated with more advanced-stage disease at diagnosis. We evaluated the effectiveness of interventions designed to increase completion of diagnostic colonoscopy after abnormal fecal immunochemical test (FIT) or fecal occult blood test (FOBT) results in these populations.
methodsWe searched six databases from inception through September 23, 2024 (updated June 4, 2025), for randomized trials, nonrandomized controlled studies, and controlled pre-post studies of interventions to improve colonoscopy completion after abnormal FIT or FOBT in health-disparity populations, as defined by the U.S. Department of Health and Human Services. Risk of bias was assessed with RoB 2 and ROBINS-I and certainty with GRADE. Studies were pooled within intervention types (PROSPERO CRD42024591109).
resultsTen studies met inclusion criteria: patient navigation (8), a registry-based quality-improvement collaborative (1), and low-touch result notification (1). In the registered primary analysis-navigation, with completion over each study's own window-navigation increased completion versus usual care (risk ratio [RR], 1.27; 95% CI, 1.10-1.46; moderate certainty). The effect was stable when all interventions were pooled as registered (RR, 1.28; 95% CI, 1.12-1.46) and across analytic choices, and was consistent in post hoc analyses at 6 months (RR, 1.29; 95% CI, 0.97-1.71) and 12 months (RR, 1.34; 95% CI, 1.20-1.49; I DISCUSSION: Patient navigation improves timely diagnostic colonoscopy completion after abnormal stool-based screening in health-disparity populations (moderate certainty); other strategies increased completion but rest on single studies. Limitations include intervention heterogeneity, varying follow-up intervals, and few studies per intervention type. Standardized time-based follow-up benchmarks and expanded navigation may advance equity. This study received no external funding.
