Epidemiological characterisation of dengue fever across Saudi Arabia.

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
backgroundDengue fever is an emerging public health threat in Saudi Arabia. To guide evidence-based vector control, this study aimed to characterise the epidemiological and clinical patterns of infections across key regions in the Kingdom between 2022 and 2024.
methodsA total of 2850 serum samples from suspected dengue patients were collected from hospitals in seven regions in Saudi Arabia. RNA extraction and dengue virus detection were conducted using standardised reverse transcription polymerase chain reaction (RT-PCR) protocols. Statistical analysis was applied to identify the sociodemographic predictors of PCR-confirmed dengue.
resultsAmong the 2850 individuals tested, 1447 (50.8%) were PCR positive. Most cases (n=1269) occurred in 2023, with Makkah alone recording 801 cases. Males represented 73.5% of PCR-positive cases, while non-Saudi nationals accounted for 47.7%. Multivariable regression showed significantly lower odds of positivity among females (odds ratio [OR] 0.65 [95% confidence interval {CI} 0.55 to 0.76], p<0.001) and higher odds among non-Saudi nationals (OR 1.17 [95% CI 1.00 to 1.38], p=0.050). Despite the relatively low caseloads, Jazan and Asir had higher adjusted odds compared with Madinah.
conclusionsDengue transmission shows strong geographic, demographic and seasonal variation, with evidence of epidemic activity in 2023. These findings underscore the need for targeted vector control and enhanced surveillance in high-risk regions.
