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: Time in range (TIR) reflects glycemic variability and is a widely used index for glycemic control in patients with diabetes; however, it is unclear whether it is associated with infectious complications after pancreatectomy. Herein, we examine the association between TIR and infectious complications after pancreatectomy. Methods: This retrospective cohort study collected cases from two different institutions, with one institution providing the discovery cohort (n=543) and the other institution providing the validation cohort (n=540). In total, 1,083 patients who underwent pancreatectomy were included. TIR was defined as the percentage calculated based on a four-point glucose test using the formula: number of times within target range/total number of tests × 100%. The target range was set at 70-150 mg/dL. TIR cutoff value was set to 75% using the receiver operating characteristic curve for the onset of organ/space surgical site infection (SSI). Results: Of the 543 patients in the discovery cohort, 210 (39%) had TIR ≥75% (well-controlled), and 333 (61%) had TIR <75% (poorly controlled). To balance the clinical characteristics, patients underwent one-by-one propensity score matching, resulting in two groups of 143 patients each. Regarding infection type in the discovery cohort, only organ/space SSI was significantly higher in the poorly controlled group in all patients (19% Conclusions: TIR <75% after pancreatectomy is a risk factor for organ/space SSI. These findings may help provide a new method for glycemic management.
