A systematic review and meta-analysis of healthcare service quality in Iran using the SERVQUAL model: a comparison before and after the Health Transformation Plan.
Synthesis 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
backgroundThe quality of service constitutes a crucial element in achieving patient satisfaction and population health. The Health Transformation Plan (HTP) represented a pivotal initiative within the Iranian health system, aimed at enhancing the quality of health services. Therefore, this study aimed to determine the effect of Iran’s HTP on the quality of health services based on the SERVQUAL model.
methodsThis systematic review and meta-analysis was conducted in 2023, following the PRISMA guidelines. A comprehensive search was performed in national and international databases, including Web of Science, PubMed, Scopus, SID, and MagIran. The quality of the studies was assessed using the 22-item STROBE checklist. Overall expectation and overall perception scores were calculated as the pooled mean values across the five SERVQUAL dimensions. The data analysis was conducted using Comprehensive Meta-Analysis software.
resultsA total of 51 studies, comprising a total sample size of 19,679, were included in the analysis. The pooled estimate of the mean for overall expectation before and after the HTP was 4.646 (95% CI: 4.48–4.81, P < 0.001) and 4.678 (95% CI: 4.29–5.06, P < 0.001), respectively. Moreover, the pooled estimate of the mean for overall perception before and after the HTP was 3.785 (95% CI: 3.56–4.01, P < 0.001) and 3.806 (95% CI: 3.53–4.07, P < 0.001), in that order. After the HTP, the highest and lowest gap was related to empathy (Gap = -0.9) and tangibles (Gap = -0.852), respectively. Additionally, there was a 0.176 decrease in the quality gap for inpatient services, a 0.02 increase for outpatient services, and a 0.24 rise for primary health care (PHC) services.
conclusionOur study shows that although patients’ expectations and perceptions improved slightly after the HTP, the overall quality gap widened, with the greatest deterioration occurring in primary healthcare. These findings underscore the need for more balanced resource allocation, stronger support for the PHC workforce, and enhanced patient-centered practices, particularly communication, empathy, and responsiveness. Prioritizing these areas may help improve service quality across all levels of Iran’s health system.
