1 · What the graph read from it

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.

2 · The registry

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

purposeScreening for adolescent idiopathic scoliosis (AIS) using the Adam Forward Bending Test (AFBT) remains controversial, resulting in the discontinuation of scoliosis screening in the Netherlands. This study aims to validate the Scolioscope, a simplified version of the Scoliometer, for detecting scoliosis in a home setting.

methodsA validation study was conducted at the orthopedic outpatient clinic of Erasmus Medical Center Sophia Children's Hospital in Rotterdam, the Netherlands. Patients aged 9-18 years with or without AIS and capable of performing the AFBT were included. The Scolioscope measurement of the parents was compared with the Scoliometer measured by an orthopedic surgeon. After unsatisfactory results with the initial Scolioscope version, a revised version was developed and tested.

resultsAmong 100 patients included in the study, 79 had scoliosis. The revised version of the Scolioscope demonstrated a positive predictive value of 97%, a negative predictive value of 89%, sensitivity of 94%, and specificity of 94%. Parental measurements showed no variation, with an intra-observer reliability kappa value of 1.

conclusionThe Scolioscope demonstrates high diagnostic accuracy and precision, making it suitable for use in at-home scoliosis screening programs.
