Variation of Procalcitonin Level in Elective Cardiac Surgery at a Tertiary Cardiac Centre: A Prospective Longitudinal Study.
Article in Health science reports, 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
Background: Procalcitonin (PCT) levels often rise after cardiac surgery due to an ongoing postoperative inflammatory response. The changes in PCT levels are useful for the early detection of postoperative infections. We assessed the variation of procalcitonin levels in patients undergoing elective cardiac surgery at the leading tertiary cardiac centre to support clinical decision-making and future studies in our setting. Methods: An observational longitudinal study was conducted among 273 adults who underwent elective cardiac surgery. Patients with perioperative signs of infections, systemic infections, and use of corticosteroids within the last 7 days were excluded. SPSS version 26 was used for data analysis. We measured baseline serum PCT levels before surgery, and on days 1, 3, and 5 after surgery. A Results: Our study showed a characteristic double peak in procalcitonin levels. The baseline PCT level was 0.10 ng/mL. Postoperatively, the median PCT values were 11.9 ng/mL on day 1, 6.8 ng/mL on day 3, and 15.9 ng/mL on day 5. The Friedman test showed a statistically significant difference in the levels of PCT at the four time points ( Conclusion: There was a dynamic postoperative variation in levels of PCT. A secondary rise in PCT levels may indicate the development of delayed complications like Surgical Site Infections and Sepsis requiring clinical attention. Therefore, monitoring serial PCT trends over time is more important than reliance on isolated values.
