Clinical course and potential associated factors of progressive calcinosis cutis in early systemic sclerosis: a cohort study.
Article in Annals of medicine, 2025. 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
backgroundCalcinosis cutis of hands can progress and impair hand function in systemic sclerosis (SSc). Understanding the natural disease and comprehensive management is crucial.
objectiveTo examine clinical course and identify risk factors associated with progressive calcinosis cutis in early SSc.
methodsDual time-point hand radiography was performed at initial and after diagnosis at median interval (range 2.9 ± 0.4 years) in 53 recruited patients with early SSc. Progressive calcinosis cutis defined as the worsening of severity according to simple soring scoring system (no, mild, moderate, severe) comparing to previous hand radiography. Odds ratio (OR) and their 95%CI were used to evaluate associated factors and calcinosis cutis progression.
resultsA total of 35 cases (155 per 100 person-year), showed progressive calcinosis cutis with the incidence of 22.6 per 100-person-years (95%CI 16.2-31.4). The most common area of progressive calcinosis cutis was at right distal phalanx, 12 of 35 (22.6%). Although statistically not significant by logistic regression analysis, elderly patients, Raynaud's phenomenon, ischemic ulcer, telangiectasia, and salt-pepper tended to be more frequent in progressive calcinosis cutis than those who had no progression. Around one-quarter of those who had no calcinosis cutis experienced worsening across more than one level of severity.
conclusionProgression of calcinosis cutis in early SSc increased over time, particularly within 3 years after the first evaluation. Elderly patients and those with vasculopathy were found more frequently. Further study with a larger cohort is needed to support these findings.
