Efficacy of different pharmacological therapies for diffuse cutaneous systemic sclerosis: a systematic review and network meta-analysis.
Synthesis in European journal of clinical pharmacology, 2026. 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
objectiveThis study aims to compare the effectiveness of different pharmacological therapies for diffuse cutaneous systemic sclerosis (dcSSc) through a network meta-analysis (NMA).
methodsRandomized controlled trials (RCTs) on pharmacological interventions for dcSSc were systematically searched in PubMed, Embase, Cochrane Library, and Web of Science up to 2026. A Bayesian network meta-analysis was carried out using Markov Chain Monte Carlo (MCMC) methods via R software and its GeMtc package. Outcomes assessed included Modified Rodnan Skin Score (MRSS), pulmonary functions (forced vital capacity [FVC], and diffusing capacity of the lung for carbon monoxide [DLCO]), and Health Assessment Questionnaire (HAQ). Effect sizes were reported as standardized mean differences (SMDs) with corresponding 95% credible intervals (95% CrIs).
resultsA total of 20 RCTs involving 1,760 patients and 16 interventions were included. The results revealed that rituximab was the most effective intervention for reducing MRSS (SMD = - 3.4, 95% CrI (- 4.2, - 2.7)), followed by cyclophosphamide (CTX) (SMD = - 2.8, (- 3.3, - 2.2)), and belimumab (SMD = - 1.5, (- 2.5, - 0.39)). Belimumab (SMD = 1.9, (0.75, 3.1)) and CTX (SMD = 1.3, (0.86, 1.8)) topped FVC improvement. Methotrexate (MTX) was the most effective for enhancing DLCO (SMD = 0.52, (0.046, 0.99)). Belimumab (HAQ: SMD = - 3.8, (- 5.5, - 2.1)) and CTX (HAQ: SMD = - 2.9, (- 3.4, - 2.3)) were significantly effective in lowering HAQ scores.
conclusionB-cell-targeted therapies (e.g., rituximab and belimumab) seemed to outperform other therapeutic agents in lowering MRSS and HAQ scores. Conventional immunosuppressants (e.g., CTX and MTX) might be more effective in enhancing pulmonary functions. Treatment strategies should be tailored according to the extent and severity of organ involvement.
