Physicians' knowledge, attitudes and practices on nuclear medicine in Cameroon: implications for medical education and health system planning in low- and middle-income countries.
Article in BMC health services research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionNuclear medicine has become a cornerstone of modern healthcare. Nuclear medicine services in Cameroon ceased in 2019, leaving critical diagnostic and treatment gaps. This study assessed physicians' knowledge, attitudes, and practices (KAP) toward nuclear medicine to guide service restoration.
methodsWe conducted a web-based cross-sectional survey of 230 Cameroonian physicians from October 1 to December 30, 2022. A structured, pretested questionnaire explored awareness, knowledge, perceptions, and practices related to nuclear medicine. Data were analysed descriptively.
resultsThe survey included 51 (22.2%) general practitioners, 80 (34.8%) residents, and 99 (43.0%) specialists. Most respondents had less than 10 years of professional experience (205; 89.1%) and were based in the Centre (104; 45.2%) or Littoral (57; 24.8%) regions. General medicine (65; 28.3%) and internal medicine (38; 16.5%) were the most represented specialties. Among respondents, 219/230 (95.2%) had heard of nuclear medicine, mainly through medical education (70/219; 32.0%). Practical exposure was limited, with 37/230 (16.1%) having visited a nuclear medicine unit, 57/230 (24.8%) having seen a nuclear medicine report, and 61/230 (26.5%) having recommended an examination. Misconceptions were frequent, with 126/230 (54.8%) considering nuclear medicine a branch of radiotherapy-oncology, 166/230 (72.2%) misidentifying equipment, and 61/230 (26.5%) believing it could be substituted by other modalities. Regarding perceptions of risk, 102/230 (44.4%) considered nuclear medicine risk-free, 76/230 (33.0%) perceived it as risky, and 52/230 (22.6%) were uncertain. Almost all respondents (228/230; 99.1%) supported re-establishing nuclear medicine services in Cameroon, 221/230 (96.1%) endorsed its inclusion in medical curricula, and 189/230 (82.2%) believed it would reduce costly medical referrals abroad.
conclusionThere is limited knowledge and practice of nuclear medicine among Cameroonian physicians, representing the primary barrier to nuclear medicine integration. Targeted and strengthening medical education, investing in infrastructure, and promoting research are essential to support the integration and scale-up of nuclear medicine services in the country and comparable settings.
