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

Study Designretrospective case-control study.ObjectivesThe objective is to investigate how preoperative sagittal malalignment affects clinical outcomes in short-segment lumbar interbody fusion.MethodsA total of 684 patients who underwent short-segment lumbar interbody fusion were reviewed with a minimum follow-up of 2 years. According to the SRS-Schwab Adult Spinal Deformity Classification, preoperative sagittal malalignment was defined as a sagittal vertical axis (SVA) ≥ 95 mm or pelvic tilt (PT) ≥ 30 degrees or Pelvic incidence (PI) - Lumbar lordosis (LL) ≥ 20 degrees in this study. Patients were divided into a well-alignment group and a malalignment group. Spinopelvic parameters such as thoracic kyphosis (TK), LL, lower LL (LLL), sacral slope (SS), PT, PI, SVA, T1 pelvic angle (TPA), and segmental lordosis (SL), as well as Visual Analog Scale (VAS) of low back pain and leg pain, Oswestry Disability Index (ODI), and Roland-Morris Disability Questionnaire (RDQ) were measured preoperatively and at the final follow-up.ResultsThe well-alignment group included 443 patients, and the malalignment group included 241 patients. In the malalignment group, PT, PI, SVA
