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.

Abstract
Background: In the 12-month, randomized, double-blind, placebo-controlled Phase 2/3 NPC-002 study (NCT02612129), arimoclomol significantly reduced annual disease progression versus placebo, measured by the 5-domain NPC Clinical Severity Scale (5DNPCCSS). Arimoclomol has been approved in the US for treatment of Niemann-Pick disease type C (NPC) in combination with miglustat. This paper introduces the rescored 4-domain NPCCSS (R4DNPCCSS) as a Methods: To more accurately assess changes in disease course over a 12-month time period in a heterogeneous group of patients, the Cognition domain was removed from the 5DNPCCSS and the Swallow domain was rescored to reflect linearity in disease progression. Rescoring of the Swallow domain was based on input from clinical NPC and swallow experts from a qualitative interview-based study ( Results: Construct validity analysis demonstrated high agreement between the R4DNPCCSS domain scores and the Clinical Global Impression Scale of Severity (CGI-S) and NPC Clinical Database (NPC-cdb) scores. Convergent validity was confirmed by strong correlations between the R4DNPCCSS domains and corresponding items on the Scale for Assessment and Rating of Ataxia (SARA), 9-hole peg test (9-HPT), and Video Fluoroscopic Swallowing Study (VFSS) performance tests. The NPC-002 Conclusion: The R4DNPCCSS is a valid and reliable measure of disease progression demonstrating consistent outcomes with the prespecified 5DNPCCSS endpoint. Arimoclomol significantly slowed disease progression through 12 months as measured by the R4DNPCCSS versus placebo.
