Uptake of influenza and pneumococcal vaccines among older adults attending primary health care centers in Riyadh, Saudi Arabia.
Article in Journal of family medicine and primary care, 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
Context: Influenza and pneumococcal infections cause substantial morbidity and mortality in older adults, particularly those with chronic comorbidities. Despite proven benefits, vaccination coverage remains low. Aims: To assess utilization of influenza and pneumococcal vaccines and identify predictors of uptake among adults aged ≥65 years. Settings and Design: Longitudinal retrospective study using electronic health records of patients aged ≥65 years attending Ministry of National Guard Health Affairs (MNGHA) primary health care centers in Riyadh, Saudi Arabia (2020-2023). Methods and Material: Demographics, comorbidities, visit frequency, and vaccination status for influenza vaccine and pneumococcal conjugate vaccine (PCV13) were extracted. Multivariable logistic regression was used to identify predictors of influenza and PCV13 uptake, reported as odds ratios (ORs) with 95% confidence intervals (CIs). Statistical Analysis Used: Descriptive statistics and multivariable logistic regression; two-sided Results: Among 18,950 patients (mean age 73.7 ± 7.3 years; 52.3% female), influenza vaccination coverage was 467 (2.46%) and PCV13 uptake was 147 (0.77%). Males had higher odds of receiving influenza (OR 1.3, 95% CI 1.12-1.63) and PCV13 (OR 1.4, 95% CI 1.05-2.03). Uptake was higher among patients with dyslipidemia, asthma, diabetes, or hypertension. Vaccination peaked in 2021 and declined sharply in 2022-2023. Dirab clinic showed the highest vaccination rates. Conclusions: Influenza and PCV13 coverage among older adults in Riyadh primary care was very low, with variation by gender, comorbidities, and clinic. Targeted interventions are needed to improve uptake and reduce preventable infectious disease burden.
