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
Objective: This study aimed to evaluate the potential prognostic value of procalcitonin (PCT) and procalcitonin clearance (PCTc) among patients with septic shock. Methods: We conducted a prospective single-center observational study of septic shock patients admitted to the adult intensive care unit (ICU) of a tertiary teaching hospital in Southern China between January and December 2015. Serum PCT levels of surviving patients were measured at the onset of septic shock and subsequently on days 2 (24 h), 3 (48 h), 4 (72 h), and 5 (96 h), respectively. Similarly, PCTc on Days 2, 3, 4, and 5 were calculated to evaluate their prognostic performance. Results: One hundred and twenty-eight adult patients with septic shock were included in the study. There was no significant difference between PCT concentrations measured at a single time point in survivors and non-survivors. However, PCTc on Day 2, 3, and 5 were significantly higher in survivors than in non-survivors. The best area under the receiver operating characteristic curve (AUC) values for prognosis were 0.74 (95% CI, 0.59-0.88), 0.74 (95% CI, 0.61-0.86), and 0.72 (95% CI, 0.54-0.90), respectively. In the logistic regression analysis, PCTc-day 2 > 12.7% and PCTc-day 3 > 49.6% were identified as independent predictors of survival for patients with septic shock. However, PCTc-day 5 was not independently associated with survival. The best cutoff for PCTc-day 2 and day 3 were 12.7% and 49.6%, respectively. Conclusion: Compared with PCTc, PCT demonstrated lower prognostic performance for the survival of patients with septic shock. However, PCTc on Day 2 and 3 were significantly associated with survival in patients with septic shock and may serve as valuable prognostic indicators.
