1 · What the graph read from it

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.

2 · The registry

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

To investigate temporal changes in the relationship between central venous pressure (CVP) and B-line scores through dynamic monitoring of the two parameters in patients undergoing transurethral resection of the prostate (TURP). A total of 101 patients who underwent TURP were enrolled in the study, with the procedure being performed under general anesthesia. B-line scores (quantified via transthoracic lung ultrasound), CVP, PaO₂/FiO₂ ratio, hemoglobin (Hb), peak airway pressure (Ppeak), arterial sodium (Na⁺), and potassium (K⁺) concentrations were measured at the following time points: baseline at the start of surgery (T0) and upon irrigation fluid volumes of 5000 mL (T1), 10,000 mL (T2), 15,000 mL (T3), and 20,000 mL (T4). Generalized additive mixed models (GAMMs) were used to analyze the longitudinal data. In the longitudinal study of 101 patients undergoing TURP, 90 were included in the final analysis. Poisson GAMM analyses revealed a significant time effect on B-line scores (F = 62.029-69.486, P < 0.001 across models), showing progressive increases from T0 to T4. CVP demonstrated a modest main effect (F = 3.156-4.026, P = 0.045-0.076) and a non-significant interaction with time (F = 1.441-1.967, P = 0.161-0.231), persisting after adjustments for age, weight, height, effective tidal volume, and intraoperative use of furosemide (adjusted pseudo-R
