Preliminary validation of the Simplified Psoriatic Arthritis Radiographic Score (SPARS).
Article in Skeletal radiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectiveTo develop and validate in a preliminary way a novel radiographic scoring system for psoriatic arthritis (PsA), called Simplified Psoriatic Arthritis Radiographic Score (SPARS). MATERIALS AND
methodsRadiographs of hands and feet were obtained from consecutive PsA patients and assessed by two readers. For each joint (30 joints in the hands, ten joints in the feet), the combination of the erosions, joint narrowing space (JNS) and bony proliferation (BP) has been assessed, giving a value of 1 for erosions presence, 1 for JNS presence, and 1 for BP presence (SPARS score range, 0-120). Reliability was assessed by calculating the intraclass correlation coefficient (ICC) and smallest detectable difference (SDD) of the readings. To determine the convergent validity, SPARS was compared to the modified Sharp/van der Heijde Score (mSvdHS) and to the Ratingen scoring system (PARS).
resultsOne-hundred and five hands and feet radiographs have been assessed. The inter- and intra-rater reliability were excellent (inter-rater reliability 0.934, and intra-rater reliability for both readers 0.845 and 0.876). The SDD for the average SPARS scores of the two readers was 8.0. SPARS correlated strongly with mSvdHS (r = 0.926; p < 0.0001), and PARS (r = 0.904; p < 0.0001). The mean time to score each of the mSvdHS, PARS, and SPARS was 14.4, 10.1, and 4.5 min, respectively.
conclusionsThe SPARS properties are close to those of the mSvdHS and PARS and is quicker to calculate.
