1 · What the graph read from it

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.

2 · The registry

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

backgroundDiabetic neuropathy (DN) is the most frequent complication of diabetes mellitus, contributing to increased morbidity and mortality. Previous clinical studies on DN in sub-Saharan Africa (sSA) have used purely clinical approaches, potentially underestimating the true magnitude of this disease. This study was designed to determine the prevalence of definite diabetic neuropathy and describe the different subtypes using objective small and large fiber function measures.

methodsThis was a hospital-based cross-sectional study that included diabetes and prediabetes patients, followed up at Jordan Medical Services, Yaoundé, Cameroon, between March 2022 and February 2023. The "Toronto Clinical Neuropathy Score" and "Douleur Neuropathique en 4" questionnaires were used for clinical evaluation. Autonomic symptoms were equally recorded. Nerve conduction studies and Sudoscan were used for electrophysiological assessments of large and small fibre functions.

resultsEighty-four participants were included; 91.7% had type 2 DM, 2.4% had type 1 DM, and 6% had glucose intolerance. DN was found in 73/84 (86.9%). Diabetic sensorimotor polyneuropathy (DSP) was the most frequent subtype (63.8%), followed by diabetic autonomic neuropathy (40.5%), mononeuropathy (36.9%), asymmetric axonal sensory neuropathy (4.8%) and treatment-induced neuropathy of diabetes (TIND) in 1.2% of patients. The prevalence of large and small fibre neuropathies was 38.1% and 25.0%, respectively.

conclusionThe prevalence of DN and specifically DSP in our study was higher than previously described in African literature. We identified subtypes never before reported in sSA, mainly small fibre neuropathy and TIND. This may have management and policy implications.
