Screening, brief intervention, and referral to treatment training for Nigerian primary care physicians: A pilot evaluation of knowledge, attitudes, self-efficacy, and barriers to implementation.

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
Substance use disorder (SUD) poses a significant public health challenge in sub-Saharan Africa, where evidence-based approaches such as Screening, Brief Intervention, and Referral to Treatment (SBIRT) are rarely integrated into primary healthcare. In Nigeria, primary care providers often lack substance use prevention training, limiting their ability to identify and manage individuals with risky substance use patterns. This pilot study is the first documented evaluation of structured SBIRT training delivered to physicians within Nigeria's primary healthcare system, assessing changes in self-reported knowledge, attitudes, delivery self-efficacy, and perceived implementation barriers. A single-group, pre-post pilot study was conducted with primary care physicians selected by the Lagos State Primary Healthcare Board. Of 33 enrolled, 25 (76%) completed both baseline and post-training assessments after a two-day train-the-trainer SBIRT course. Baseline data were summarized descriptively, and pre-post changes were analyzed using Wilcoxon signed-rank tests with rank-biserial effect sizes and 95% confidence intervals.At baseline, 9% (3/33) had prior SBIRT training, 79% (26/33) were unaware of validated screening tools, 36% (12/33) believed all SUD cases required referral regardless of severity, and 33% (11/33) viewed SUD as a moral failing. Post-training, significant changes were observed across all self-reported domains (r = 0.45-0.85, p < 0.05). Training satisfaction was high (94%), although time constraints and clinical workload were cited as key SBIRT implementation barriers. In this pilot study, structured SBIRT training was associated with improvements in primary care physicians' self-reported knowledge, attitudes, and delivery self-efficacy. Addressing time and workload barriers may support sustainable implementation in the Nigerian primary healthcare system.
