Peripheral blood perfusion in patients with systemic lupus erythematosus and in primary Raynaud's phenomenon.
Article in European journal of rheumatology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveThis study aims to evaluate blood perfusion (BP) in various cutaneous regions of the hands and face in patients with systemic lupus erythematosus (SLE) and primary Raynaud's phenomenon (PRP) and healthy subjects (HS).
methodsA total of 20 patients with SLE, 20 patients with PRP, and 20 HS were enrolled. BP was detected by laser speckle contrast analysis in different regions of the hand and at the facial level. The absolute nailfold capillary number (CN) was assessed by nailfold videocapillaroscopy.
resultsPatients with SLE and PRP had significantly lower BP levels than those of HS in 3 hand areas (fingertip, palm, and periungual; p<0.01). However, the SLE, PRP, and HS groups had comparable BP values at the hand dorsum and face. The BP and CN values revealed a positive correlation in the periungual, fingertip, and palm of hands (p<0.01), only in patients with SLE.
conclusionOur data demonstrated a correlation between functional and morphological microvascular impairment in patients with SLE.
