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
backgroundHip screw cutout is among the most common causes of intertrochanteric fracture fixation failure using dynamic hip screws (DHS). This study aimed to evaluate the effect of using an additional anti-rotation screw on hip screw migration or cutout in intertrochanteric fracture fixation. MATERIALS AND
methodsWe screened 488 patients with unilateral fragile intertrochanteric fractures treated with DHS between January 2001 and March 2016. The inclusion criteria were as follows: (1) age ≥ 50 years; (2) low-energy injury; (3) follow-up of at least 6 months; and (4) short barrel plate used in the operation. The exclusion criteria were as follows: (1) combination with other fracture; or (2) pathological fracture. Subsequently, 166 patients were enrolled; of them, 128 underwent surgery using DHS with an additional screw (Group 1) and 38 patients underwent surgery without an additional screw (Group 2). We compared the postoperative results and clinical outcomes while focusing on screw migration and cutout. Furthermore, we investigated the risk factors for lag screw migration.
resultsBone union was achieved in 160 patients (96.4%) without secondary intervention. Two patients (1.6%) in Group 1 and 1 (2.6%) in Group 2 developed screw cutout, while 18 (14.1%) in Group 1 and 12 (31.6%) in Group 2 developed screw migration. Thus, Group 2 demonstrated a higher screw migration rate. Multiple logistic regression analysis revealed that the additional anti-rotation screw was the most important factor in preventing screw migration (P = 0.019).
conclusionThe additional anti-rotation screw reduced the lag screw migration rate following DHS surgery for intertrochanteric fractures. LEVEL OF EVIDENCE: Level IV, retrospective series.
