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 study.

objectivesTo identify the factors that determine segmental lordosis angle (SLA) at L4/5 after oblique lumber interbody fusion (OLIF).

methodsA total of 65 patients who underwent single-level L4/5 OLIF (6°-lordotic cage) with posterior pedicle screw fixation without posterior osteotomy for lumbar degenerative disease were analyzed. The SLA was measured preoperatively (pre), postoperatively (post), and at the last follow-up (last) (at least 12 months) on the midline sagittal CT views. Demographics, surgical, and radiological factors were included. Clinical outcomes (ODI and VAS) were assessed.

resultsThe mean preoperative SLA at L4/5 increased from 7.1 ± 3.9° preoperatively to 9.8 ± 3.4° postoperatively (P < 0.001) and was maintained as 9.1 ± 3.5° at the last follow-up (P < 0.001). Multiple regression analysis revealed that Pre-SLA, cage position and cage subsidence were predictors of Last-SLA. Small-angle group (Pre-SLA < 6°) showed a stronger capacity in the increase of SLA (Pre-SLA - Post-SLA) and change of SLA (Last-SLA - Pre-SLA) than large-angle group (Pre-SLA ≥ 6°). Anterior cage position is associated with the more increase of SLA than posterior cage position. Cage subsidence led to approximately 3° in decrease of SLA (Last-SLA - Post-SLA). No significant correlation was observed between Last-SLA and clinical outcomes.

conclusionThe Last-SLA is strongly associated with the Pre-SLA condition and OLIF has a higher capability to restore SLA in patients with a smaller preoperative SLA. To achieve a greater SLA, surgeons should try to insert cage in the anterior disc space and reduce the occurrence of cage subsidence.
