Efficacy and safety of rituximab versus intravenous cyclophosphamide for systemic sclerosis-associated interstitial lung disease: a retrospective cohort study.

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
backgroundThe efficacy of rituximab (RTX) for the treatment of systemic sclerosis-associated interstitial lung disease (SSc-ILD) has not been fully established. This study compared the efficacy and safety of RTX and intravenous cyclophosphamide (CY) for SSc-ILD.
methodsThis retrospective study compared the efficacy and safety of RTX (20 patients) and CY (30 patients) after adjusting for the stabilised inverse probability of treatment weighting based on propensity scores. The efficacy endpoints were the absolute changes in forced vital capacity (FVC) and serum Krebs von den Lungen-6 (KL-6) levels from baseline to 6 and 12 months after treatment. The incidence of progression based on the definition of progressive pulmonary fibrosis was also recorded. The safety endpoint was the frequency of adverse events.
resultsThe clinical characteristics of the two groups were well-balanced after adjusting for confounders (i.e., FVC, nintedanib use, and newly diagnosed cases). From baseline to 6 and 12 months after the start of treatment, the median FVC increased by 50 and 60 ml in the RTX group and 40 and 15 ml in the CY group, respectively, with no difference after adjustment. The changes in serum KL-6 levels and the incidences of progression were identical in both groups after adjustment. The overall adverse events were similar in both groups after adjustment.
conclusionsRTX demonstrated comparable safety and efficacy as CY in patients with SSc-ILD. Thus, RTX may be an alternative to CY for the treatment of SSc-ILD.
