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
aimsTo evaluate associations of the indicators of glycemic control, HbA1c, continuous glucose monitoring (CGM)-derived time in tight range (TITR; 70-140 mg/dL), and time in range (TIR; 70-180 mg/dL) with albuminuria and diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM).
methodsThis cross-sectional study included 697 patients with T2DM. Albuminuria (UACR ≥ 30 mg/g) and DKD (eGFR < 60 mL/min/1.73 m² or albuminuria) were assessed. Multivariable logistic regression analyzed associations of TITR, TIR, and HbA1c (continuous/tertiles) with albuminuria and DKD.
resultsAmong the participants, the prevalence of albuminuria and DKD was 34.6% and 37.9%, respectively. After full adjustment, higher TITR and TIR were independently associated with lower odds of albuminuria (TITR: OR 0.98, 95% CI 0.97-0.99; TIR: OR 0.98, 0.96-0.99) and DKD (TITR: OR 0.98, 0.97-0.99; TIR: OR 0.98, 0.96-0.99). The highest (vs. lowest) tertiles of TITR and TIR had significantly reduced risks (for albuminuria; TITR: OR 0.36, TIR: OR 0.42; for DKD, TITR: OR 0.35, TIR: OR 0.40; all p < 0.001). HbA1c showed weaker threshold associations (highest tertile ORs: albuminuria: 2.31, DKD: 2.31; p < 0.05). However, the AUCs for TITR, TIR, and HbA1c showed no significant differences. Restricted cubic spline analysis demonstrated a significant dose-response relationship, wherein higher levels of TITR/TIR were associated with progressively lower risks of albuminuria and DKD. Subgroup analyses revealed that diabetes duration significantly modified the association of TITR (P for interaction ≤ 0.021), with stronger inverse associations observed in patients with diabetes duration ≥ 10 years. In contrast, TIR showed a consistent association across diabetes duration subgroups.
conclusionsBoth TITR and TIR are independently associated with albuminuria and diabetic kidney disease. While TIR serves as a consistent marker across different disease stages, TITR may offer refined risk stratification, particularly in individuals with longer diabetes duration. These metrics provide complementary value to HbA1c for assessing renal risk. CLINICAL TRIAL NUMBER: Not applicable.
