Pulmonary Congestion and Anemia in Hemodialysis: The Potential Link to Inflammation.
Observational study in International journal of molecular sciences, 2024. 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
Pulmonary congestion (PC) is common in hemodialysis (HD) patients. We explored the association of anemia and pulmonary congestion in HD patients. A prospective pilot observational study included 18 patients on maintenance HD. Individual B-lines scores (BLS; 8-sites method) were obtained by lung ultrasound, before and after the first two consecutive HD sessions of the week (HD1-HD2), with different inter-dialytic intervals (68 vs. 44 h). Bioimpedance spectroscopy body composition (BIS) was performed before each HD session. Hemoglobin (Hb) levels, in addition to circulating markers of chronic inflammation (soluble urokinase Plasminogen Activator Receptor [suPAR], soluble Suppression of Tumorigenicity 2 [sST2]) were obtained. Mean (±SD) BLS values were quite elevated at all time points: Pre-HD1 (16 ± 5.53), post-HD1 (15.3 ± 6.63), pre-HD2 (16.3 ± 5.26) and post-HD2 (13.6 ± 5.83), respectively. No direct significant correlation was found between inflammation markers levels and BLS. However, mean levels (±SD, ng/mL) of suPAR pre-HD1 (7.88 ± 3.07) and pre-HD2 (7.78 ± 3.02) remained significantly above the normal range (<4 ng/mL), and sST2 levels reached 2-fold the upper normal value in most patients (27.4 ± 17.8). Pulmonary congestion reflected by BLS was negatively correlated to Hb levels pre-HD1 (R² = 0.439,
