Prevalence of dyslipidaemia and low-density lipoprotein cholesterol target attainment: a descriptive cross-sectional study among adults in the Western Province of Sri Lanka.
Article in BMJ open, 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
objectivesTo assess the prevalence of dyslipidaemia and associated risk factors, and evaluate low-density lipoprotein cholesterol (LDL-C) target attainment among adults in the Western Province of Sri Lanka.
designCross-sectional epidemiological study.
settingWestern province, Sri Lanka.
participantsParticipants were recruited through a community-based survey of non-institutionalised adults aged ≥20 years residing in the Western Province for at least 1 year (n=1800), using multistage stratified random cluster sampling. PRIMARY OUTCOME: Dyslipidaemia was defined according to the National Cholesterol Education Programme/Adult Treatment Panel III guidelines. Prevalence estimates are presented with 95% CIs. Multiple logistic regression results are reported as adjusted ORs with 95% CIs. SECONDARY OUTCOME: Cardiovascular risk in participants aged ≥40 years was assessed using the WHO laboratory-based cardiovascular disease (CVD) risk chart for South-East Asia. Achievement of LDL-C targets was evaluated according to the Sri Lankan guidelines on management for dyslipidaemia management.
resultsData from 1333 subjects were analysed. Mean age was 49.8 (±14.9) years. The majority were females (63.6%). The age-sex standardised prevalence of any form of dyslipidaemia was 73.3% (95% CI 70.9% to 75.7%). Age standardised prevalence in females was 77.1% (95% CI 74.3% to 79.9) and males was 69.3% (95% CI 65.3% to 73.3%). The most prevalent type of dyslipidaemia was low high-density lipoprotein cholesterol (HDL-C) (46.6%, 95% CI 43.9% to 49.3%), followed by high LDL-C (32.5%, 95% CI 30.0% to 35.0%) and high triglycerides (21.7%, 95% CI 19.5% to 23.9%). Low HDL-C was positively associated with smoking (OR: 1.89, 95% CI 1.16 to 3.18) and inversely with male sex (OR: 0.29, 95% CI 19 to 0.45) and physical activity (OR: 0.71, 95% CI 0.51 to 0.99). Elevated LDL-C was associated with male sex (OR: 1.84, 95% CI 1.2 to 2.89), diabetes (OR: 5.34, 95% CI 3.53 to 8.08), and hypertension (OR: 1.62, 95% CI 1.18 to 2.23). Male sex (OR: 1.85, 95% CI 1.08 to 3.18), diabetes (OR: 1.9, 95% CI 1.4 to 2.58) and hypertension (OR: 1.81, 95% CI 1.12 to 2.91) were positively associated with elevated triglycerides, whereas urban sector (OR: 0.54, 95% CI 0.32 to 0.91) was protective. Physical activity (OR: 0.65, 95% CI 0.44 to 0.98) and male sex (OR: 0.52, 95% CI 0.31 to 0.89) inversely associated with any form of dyslipidaemia, whereas diabetes (OR: 7.08, 95% CI 3.99 to 12.55), hypertension (OR: 1.93, 95% CI 1.36 to 2.73), and body mass index (OR: 1.06, 95% CI 1.01 to 1.2) were positively associated. The majority of participants (66.6%) had a <10% 10-year CVD risk, of whom 64.9% (95% CI 60.1 to 69.8) did not achieve the LDL-C target of <3.0 mmol/L.
conclusionsThree-fourths of adults in Western Province, Sri Lanka had any form of dyslipidaemia, more common in females. Low HDL-C was the most frequent abnormality. Most participants aged above 40 years were at low cardiovascular risk, yet two-thirds failed to meet LDL-C targets. Non-communicable disease prevention in Sri Lanka should expand through population-wide strategies, including awareness campaigns, promoting self-monitoring, targeted education and surveillance to evaluate interventions.
