Trends and predictors of caesarean section in Thailand before and during the COVID-19 pandemic: a retrospective analysis of national hospitalisation data under the Universal Coverage Scheme.
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
objectivesSince 1985, the international healthcare community has recommended the ideal rate of caesarean section (CS) to be 10%-15% at the national level. The literature has reported that overused CS without necessary medical indications can be harmful to both maternal and child health. To generate evidence to support policy on CS, this study evaluated the trend over time of CS in Thailand during January 2016 to October 2021 (which included the COVID-19 pandemic period) and explored predictors of CS use. DESIGN AND
settingThis study was a retrospective secondary data analysis of de-identified hospitalisation data under the Universal Coverage Scheme (UCS) from the National Health Security Office's e-Claims database. Descriptive analyses were conducted to explore the number and rate of CS over time and across different characteristics (ie, age, hospital type, COVID-19 status and delivery day) including a multivariable logistic analysis to explore predictors of CS. Interrupted time series analysis was adopted to investigate the effect of the COVID-19 pandemic on CS rate.
participants569 321 CS cases under UCS from 2016 to 2021.
resultsThe results showed an increasing trend of CS rate, from 30% in January 2016 to 35% in October 2021. Both clinical (eg, medical indication and age) and non-clinical (eg, region and day of delivery) factors were significantly associated with CS. Furthermore, the COVID-19 pandemic had no significant effect on CS rate (level: -0.0016, 95% CI -0.0085 to 0.0053, p=0.66).
conclusionThis study highlighted an increasing trend of CS in Thailand and could present supportive evidence that Thailand might have been facing an overuse of CS. More awareness and actions are warranted to ensure the movement towards reduction of unnecessary CS in Thailand.
